If your going to buy a single stage for this, which is a good idea IMO, you may as well go with an RCBS. They're life time warranty and customer service is second to none, it really is some of the best out there. I just sent an old RS3 into RCBS that I bought new in 1984-ish. I managed to wear it out, but RCBS sent me back a brand spanking new RS5, which is the exact same frame as the newer RS5, but with a few nice upgrades.
The threads are steel, it has a nice large ball handle, well designed linkage for better leverage, and it can be converted to a progressive, great little press for the money. I think they go for around $120.
