Ricoh GR1
Nikon 28Ti
Minolta TC-1

BUT: they're all pricey, and I don't think any of them allows full manual control - just exposure compensation and/or fiddling with the ISO setting.

EDIT: I should say "tend to be pricey". Just saw the GR1 currently listed in the classifieds, as mentioned by John - that's a good price for a GR1.
