I've owned 3 DD (all technics) and 2 belt. The technics sounded nice and were built like tanks, but they weren't as quiet and the belts. I think the best dd I had was a sl1700?? and it was a good sounding tt (once I mated it with a good cartridge), but it was sold once I picked up a newer dual belt. That was the turning point for me. As for the build quality, the 1700 had it all the way, but the dual just sounded better. I'm now using a musichall mmf5 which smokes them all. I think all in all you are going to get what you pay for (a cheap belt is going to sound like shit), but in the $300+ range belt is going to sound better imho. I have listened to a totl vintage Yamaha DD with a v15 that sounded damn nice, but that was an expensive and complicated machine dedicated to music listening in DD's heyday.
