Which turntable should I buy?

My personal recommendation is to eliminate the Thorens from your list and buy either the Scout or the Nottingham. Of the two, I think the Scout represents the better value (price vs. performance), particularly given the excellent JMW 9 tonearm that is part of the package. And, if I remember correctly, the Scout offers an upgrade route to the Scoutmaster, which is an excellent TT.

One more consideration is find a good used LP12 from Linn.
It is a great TT and can be modified forever.

When it comes to turntables there is an embarrasmnet of riches these days.
What bothers you most? Lack of tempo? Feedback? Are you a tinkerer? Are you like Ron Popeil-set it and forget it? Do you have springy floors and lots of foot traffic? Is this budget for turntable only or will you be needing an entire front end as Raul suggested? Do you need upgradeabilty?Suspension or non suspension? Vaccum hold down? Why don't I introduce you to Shaundra? In addition to having a gorgeous set of legs she is our analogue specialist...
Just for fun she'll demo the lovely AVID DIVA at $2500 sans arm. For a picture, See Sterophile Vol 27 No 4 pg 36. Should you be needing an arm and cartrdige, might I suggest the Well Tempered arm with Lyra Helikon.
Disclaimer: I own Vpi Aries. I have not heard this Particular Avid. I auditoned a different model in thier line.

Thanks for your responses, my budget would be for the 'table and arm only. Cartridge comes next...

My preference is for speed and dynamics not bass or lushness -- I get plenty of that from the tubes ;-)
