towboater,
aim has the m44 and chinese type 53 (chinese m44), but don't be afraid of the 91/30...good gun. aim has them and they never overstate the condition. here's the catalog page:

if you're looking for a cz82, i wouldn't wait too long, they seem to be drying up...if you don't want to deal with 9mak ammo, the cz83 is the same gun, but in .380acp. southern ohio gun has both and both are good values.
imo, the nagant revolver is ok for an experienced reloader...very expensive to shoot with factory.
