I have one of the big Hornady case prep machines. I would not but another. The case trimmer works, but does not cut as cleanly as others. Cutting speed is slow. Adustment takes a while and there are no scales on the adjusting mechanism, so you have to adjust a bit and measure with calipers until you get it right.
The other stations function fine, although they're also kind of slow in my opinion. After giving it a chance for quite a while, the only thing I use the entire tool for now is to ream primer pockets. I can keep both a small and large reamer on hand and it works quite well for that.
Save your money. I use other tools for trimming cases (L.E.Wilson, a WFT and one of the new Trim-It trimmers), and I use a drill press when quickly chamfering or deburring bulk amounts of cases.
