Baikal MP53 is a nice easy to use and pretty accurate springer
Weihrauch HW40 is a nice easy to use and pretty accurate single stroke pneumatic, better trigger than the Baikal MP53
Weihrauch HW45 is a bit of a beast, much harder to shoot accurately then either of the two above.
Baikal MP46 is a very nice very accurate single stroke pneumatic match grade pistol.

Plenty of other good pistols will be suggested, but perhaps if you could handle a few and see what suits you?
