I have a Romanian - these are the ones that take one round at a time for feeding, with a twitch of the loading lever. It works very well - I paid $105 about 8 years ago - they went up to around $140, and have now come down to around $95 - 100.
The other type that I have seen, but never used, and have some feedback from customers is the Chinese type (as posted by Savage re: cdnn) - these are the type with the front opening panel that you load then wind up. They are supposed to be excellent, in general with a stinker thrown in now and then. The CDNN price of $70 is very attractive - if they work as intended.
