Advice - What turntable should I buy ???

I have to disagree with Dentdog. I had a $12K digital player at the time I bought my MMF5 and I was able to appreciate what analog had to offer, even with that huge price disparity.
Yes, a very good analog front end has it's virtues, but I think an MMF7 will let you test the waters without a huge financial commitment.

White Rega RP3 w/upgrades currently selling for $850.00
Dynavector P-75MKII currently selling for $450.00
Audio Technica OC9 MKIII currently selling for $395.00

You may never listen to your CDs again.

Clearaudio, VPI, or Music Hall has good starting turntable/arm/cartridge combo at around $1000~$1500.
I currently have a clearaudio bluemotion. It is easy to install and setup.

One you start enjoying vinyls, as with many audio enthusiasts, you you may get an upgrade bug.
The first thing you may consider would be upgrading the stock cartridge, then move to MC cartridge, SUT, then ... Along the line, you may want to purchase an additional turntable for mono cartridge.

Until then, enjoy your vinyls.

A Clearaudio Concept or a VPI Traveler are IMHO a standout best buy. The Traveler lists for 1500 but is sometimes even being offered with a Ortofon 2M red, which is easily upgradable to blue just by changing the stylus at a later date. The new Scout JR is planned to take its rightful place. Either table is good enough to grow into. You could without reservation put a $800-$1000 cartridge on either of them and still feel like it was appropriate for the rig you are putting it into, especially something like yours. If you like the BBC sound a used Linn LP12(80's Vahalla), or axis is also a really good way to go. New they sell for a fortune. Rega RP6 with a Sumiko Blue point EVOII comes in at about 2K new but also can be a very compelling match. If you want to stay at 1K or less, a Rega RP3, VPI Nomad or scout (acrylic platter) may be just the ticket with a modest cartridge. Unfortunately the Clearaudio product line is out of contention at this point. Unless you are lucky enough to find one with a MM cartridge used (about $1200 right now). A used VPI traveler sometime shows up too at about the same price sometimes, particularly the first generation. Any of these choice would sound great on your rig.

My humble opinion from my 25 years in this hobby. By the way I also own the Oppo 105, so flexible and good-sounding.

If you can strike a used Marantz TT-15S1 it should be within your price range. Here are my reasons for going this route.

1. It is real eye-candy for the money, and in my book, looks count with those audio toys. This philosophy applies to my current amp and speakers. Since this turntable is solid high-quality white acrylic, it is quite something. I put a $ 10 IKEA LED light hidden behind the table, and it makes a wonderful and soothing sight in a darkened room as the whole thing lights up.

2. Sounds exceptionally good for the money, and this in part because it comes with a nice Clearaudio cartridge. I have seen this cartridge priced from $600 to $750.

3. It is NOT a Marantz table but in fact made in Germany by Clearaudio, a most reputable manufacturer. Marantz had it made for them, and the TT-15 comes with better feet and a more sturdy feel than the equivalent Emotion Clearaudio table that the Marantz table is inspired from. You will read in some reviews than the M is actually an upgraded Clearaudio Emotion for less money.

4. The Satisfy arm is great on it and easily adjustable, unlike Regas. Everything is nicely machined, and the motor is very quiet and makes no contact with the table.

5. My previous table was the Music Hall mmf-7, a universally-acclaimed best buy. However, the Marantz is much, much quieter and the mmf put out much higher surface noise. Just do a slight fingernail-tab on the deck of both, no-contest.

Please take into account that I am NOT a vinyl junkie, and that I use my table sparingly. However, I know a good-sounding unit when I hear one.

The Marantz is of course no 3K VPI machine, but for the money, again, it is a fine purchase.

Hope this helps, finally here's a review I found interesting a few years ago...
