Dr. Strangelove, you seem to be one of those happy sneakers who find value for almost nothing 🙂 You mention prices in euros - where you are ? As my only reasonable option to feed GAS is big auction site, I just love thrift store prices mentioned on Net.
For example, only time I have seen BMF 2.8 on UK site, it went off for ~45pounds. Agree, that sometimes Mju/Epic described "like new" touch very high price tag (yeah, using pouch for P&S pays back 🙂 )
After my mju which I bought new for almost ~200USD (local price) had problem, I got one for spare parts and don't concentrate on them. I fell back towards 80's P&S, and right now I'm waiting for Canon MC and Ricoh FF-70. Btw, I also noted that samples from Ricoh AF-2 (and AF-5 seems to be similar) look good, with appealing contrast.
Maybe some RFF'ers can point to resorces or tell more about lens designs - those little Tessars and Mju bright lens are about 4/4 design, and I wonder that 5/5 are so rare (to mention FF-70 and PC35AF), what are their advantages and weaknesses, well - just to feed mind with theoretical stuff (as good pic can be made without lens at all, as we know).
