there is a used Lenco L-75 jean natais plinith with a vpi 10.5i tonearm in mint condition that someone is selling on the gon' for $3,000. This is a great price. You can then get a used tt cleaner for $1,500 and buy a cartridge for $1,500 (dynavector or shelter to name a few) and you will be in analog heaven. The added $1,500 you are willing to spend above that can be spent on buying lps. Well maybe less than $1,500 because you do need to stabilize the tt on a good platform that mapleshade can hook you up for a few hundred.
I started with the technics direct drive and yes its a great starter tt but since you have already been exposed to your friend's higher quality rigs, I see no reason given your ample budget to not jump in head first. By purchasing a quality name used, you have little to fear by way of losing money if you ever decide to sell. The lenco with natais plinith is great bang for your buck especially used. You have an upgrade path too in that later you can put a graham phantom arm or an even pricer cartridge on it.
yes you can try a lot of turntables but the sooner you pull the trigger on one of the can't go wrong used turntables, the sooner you can start enjoying analog. I still enjoy digital too so don't lose all perpective because some recordings on lp are not better than digital or are so rare or so expensive that the digital version is still a pretty good bet.
