These are fantastic cameras. Solid, reliable. The meter is great. Very underrated. Mirror slap is noisy but no more so than its contemporaries.
The dsb lenses are OK. You can find ML-series lenses for reasonable prices on the auction site or, possibly by posting a WTB post here on APUG. I gave away a DSB zoom lens last year. It was a fine performer. Noticeably better than the kit lens that came with my work EOS Rebel T3 (DSLR) ... for my personal work, I don't use zooms so I never used it with film.
EDIT: I think the zoom was a 75-200.
