Ok well you can usually pick up a JVC QL 5/7 on eBay for $300-500 (there are some currently on there)
Turntable $300-500
Cork piece to put on top of the rubber mat $8-12
Sumiko Pearl with shim mod and a tiny piece of clay in the stylus gap $120
Non-hardening clay 4.5lbs $25
Screws $5
Belden 8402 IC's $80~ eBay (only necessary if we need a phono preamp to preamp IC for this to be complete list)
That leaves $263-463~ to build a Salas phono preamp. ($60 for PCB, $64 mini kit, $10 matched transistors, $8 PRP resistors, $30 PSU boards, C7 $24, $100 enclosure, $50 for chassis stuff)
$838-1088 depending on a little this and that, price of TT.
You put screws into the bottom side of the TT and pack it with clay to add some mass. This setup will blow away most people if setup well. (knowing how to setup a cart, and knowing when to add a little extra overhang for example, like necessary on some cart/arm combos)
If you want to upgrade later a new plinth for the TT is a nice idea. Some people prefer this TT over ones they've had for huge sums of money, once it's in a heavy plinth. I think it's better if you plug it into a little bit of a filter and change the power cable ($100).
