I'm happy with my E-P2 + Panny 20mm f/1.7, but recently I wanted to use some old MF lenses I own and so I have to buy a couple of adapters (M to M43 and FD to M43). I've seen many of 'em on ebay, in different ranges of price; the point is that I've read somewhere that cheap adapters may damage the camera? Is it true? Do you know some safe adapter that doesn't cost 200 bucks? I've seen those of Fotodiox and they seem the right thing, are those safe?
