As a general comment, the prices that Minolta Manual Focus gear is selling for nowadays on ebay is unbelievably low.
I just picked up 3 very good lenses for completely ridiculous prices: Yesterday, I paid $19.99 INCLUDING Shipping for a pretty minty 80-200mm f4.5 MD Rokkor-X.
And I also paid $8.50 plus $8 shipping for a Kiron 28-70mm f3.5~4.5 MD mount zoom, and $19.99 plus $10 shipping for a Vivitar Series One 100-500mm f5.6~8 Zoom. In each case, I got these for the starting bids because I was the only bidder on the items.
And in the last couple of weeks, I got a good working XD-11 body for $35, a really beautiful XE-7 body for $30, and a true mint X-570 for $17 including a 50mm f1.7 MD lens, and a Winder D for $12. These prices are unbelievable for the very best Minolta gear. The prices are running around 1/3 the prices of comparable Nikon gear, and even noticeably lower than Canon FD gear, which is probably a more relevant comparison because it's a similarly dead end lens mount.
