I didn't realize I wasn't supposed to do that, I've taken the link down. Thanks for the heads up and all the info!

which leaves the SL-Q303 for $250... Seems to be a decent price in comparison to what I see SL-1200's for on ebay...
I don't think I need the top of the top of the top... but is the Q303 a pass?

One thing to keep in mind is that with the manual Technics decks, any one of them could have been pressed into DJ service and have suffered just as much abuse as a SL-1200 series. I've had a SL-1800 (original) where the previous owner cranked the suspension down completely tight and managed to dent the tonearm wand and pooch the tonearm bearings during use. I've also got a pair of SL-1500 Mk2 turntables that were DJ rental units ... you cannot imagine!
With regards to the SL-1500 and replacement tonearms, there was also the SL-150, in both original and Mk2 versions, which were sold without tonearm. The original version was configured to use the SME 3009 tonearm. It doesn't have a hole cut in the base / rear foot support to allow for clearance with the bottom portion of the vertical pillar / interconnects of many other tonearms. Of course the SL-1500, never designed to have its tonearm replaced, would have the same issue. So some surgery on either may be required. The Mk2 version of the SL-150 does have a hole in the base and even came with foot extensions to raise the base up to provide for clearance. Not sure if the hole would have to be enlarged for some tonearms (which is the case with a number of tonearms retrofitted to the SL-1200 series ... and as a side note there was also a SL-120 (original) and SL-120 Mk2 versions that sold without arms). All these non-arm versions are fairly rare.
The later SL-1800 (original and Mk2) didn't have a separate '180' version. Probably because it's also a 'suspended' design which further complicates retrofitting with a replacement tonearm.
