I purchased one on Ebay several weeks ago. I wish I would have read Whiz White's web site before I bought one. He has the info you need to know before purchase.
The one I bought needed a lot of work before it loaded a shell properly. If you are mechanically inclined then, providing you get it reasonably priced, it could make you a great reloader. These loaders are not for the faint of heart!
Whiz has an article that is a "must read" in my opinion, prior to purchase. I have included the link to it above.
I purchased a old 800B for parts pealing paint covered in dust from sitting for years. Got it home cleaned it up real well adjusted and lubed the joints and it works perfect. Looks like hell but the shells look like factory what a pleasant surprise I just like the feel and click of the 800B. I also enjoy setting the PW;s up once they are right they are a joy but I;m a addicted tinkerer at heart and that is a good thing as PW's can give you a run for your money when they are not adjusted properly but the dealers are very helpful when advice is needed.
