Salty,
You won't be sorry, I bought mine in October and I have run probably over 10,000 rounds through it between what I have prepped and what I have loaded and I love it. I think everyone here has pretty much summed it up that since it is mechanical there will be problems and there will be a learning curve. I would have say that 99% of the few problems I did encounter were contributed to a lack of experience with the machine. The more I use the press the only problems I have now seem to be related to the cases. Occasionally a dinged rim will cause it not to feed into the shell plate or allow the extraction wire to kick it out.
The best advice I think I can give you is don't try to reload anything on it until you set it up and run a lot of cases through it first. When I got mine I got the case feeder at the same time so it needed to be setup too. So I probably cycled 1,000 casings through while I was setting it up to make sure I had all the timing setup correctly and that I got a good feel of how it was suppose to feel when running normally. I didn't do this with the first progressive press, a Lee LoadMaster, I had and may be why I was never really happy with it. Do continue reading all the threads on the Hornady AP there is a wealth of information out there by many of the folks who have have posted here on your thread. If you do run into problems don't hesitate to ask I know DaveInFloweryBranchGA has definitely helped me diagnose problems with the extraction wire when I first started.
