Cheap used mirrorless: Oly E-P1 vs. Nex 3 vs. Samsung NX100

I recently bought by chance an Olympus E-P1 that allowed me to use a couple of short registration distance lenses. I like it in particular because the camera aspect fits well with old lenses, but... 2x crop factor is too much. I'm thinking to switch to another cheap body, like Nex 3 or NX100. Any arguments in favour or against (regarding MF usage, no other lenses on this one)?

The Samsung is (for me, now) the cheapest solution. Registration distance on NX100 is greater than Sony, and I do not know if this is truly limiting (I have a couple of M39 lenses at present). Focus peaking? I understand NX100 has something similar, how usable is?

thanks people.

IIRC, the nx100 has only 2x focus magnification, that is really not enough for me (I rely much more on magnification than on peaking)
Having just bought a nex 5r I did some research on mirrorless cameras, and considering sensor size, lens adaptability and mf friendliness - for my taste - a nex-3 is still an unbeatable bargain.
I bought the 5r both because i found a cheap one (440€ with the 16-50 pz) on amazon, and because the hybrid af system may come handy when shooting video - that is something I plan to do quite often.

I have NEX-3 and NX100. NX100 is poor for use with manual lenses as it only has 2x magnification and no other aids.

So +1 on the NEX-3, I dearly love mine, had it 3 years and still don't feel the need to upgrade.

Ok, thanks to both . Now I will try to sell my otherwise splendid Oly...

Some report: I was able to sell the E-P1 and buy a Nex-3, that is now the host for 3 lenses (soon becoming 5 ).
