I'm going to take the average down some.
Somewhat DIY turntable with entirely DIY tonearm. Somewhat on the table, because the motor/drive is pulled from a Technics SL-6 (linear tracker). I ordered one of these on eBay and the tonearm carriage had a stress fracture on plastic part that holds the linear bearing. Ordered a replacement part (a used part of course), same break. So pulled the platter/motor, figured out the wiring/voltages, and built my own.
Made my own arm. Started as a pretty typical unipivot. I tried a couple methods of restraining the roll, ended up with elastic bands, which also provide a degree of damping. Latest wand design has the counterweight attached directly to it. Counterweight is Sorbothane, which provides some damping of energy that makes it past the cartridge and into the arm, if you look closely, you'll see it is the same as the 3x Sorbothane feet.
Wiring is shielded, which makes for a nice quiet background, I just took the resistance of the shield/jacket into consideration when determining anti-skating. The switch controls 33/45-RPM. I actually don't have any 45-RPM music, but do have some 45-RPM test records.
Right now I'm mostly using the Realistic 42-2109 phono preamp I modified, removing the on-board power supply components save for the final cap, and I run an external 24vdc linear/regulated wall wart. It was pretty darn quiet to start, it is very quiet now. This 42-2109 has also had the parts upgrade from eBay to swap all the old components (caps, etc.) with newer stuff. I like the sound a lot.
Not pretty like all the other stuff posted in this thread, but it is nice to listen to.
