I've got a FA case prep center and it's a pretty good deal IMO. Tool heads are easy to change out, can swap out to a better quality if desired. I have used a Hornday & RCBS crimp remover on mine, both worked fine, comes down to personal preference on these. Primer pocket cleaner is ok, chamfer and debur tools are ok for my needs (no competition or high precision loading). The trim function is collet based, fairly easy to adjust/set the trim length, but it seems like I push pretty hard to get the cutting head to trim, and it makes a gawd awful squeal when trimming. I think it's primaryly due to the slow RPM speed on the trim function.
I'm exploring other trim options right now but seem to prefer the old Lee case trimmer from the dark ages. I did upgrade to the round ball cutter model but have not used it yet. Using a small 12v drill, I get no "squeal" in the trim process, it's just a PITA using the lock nut to hold each case. That squeal on the FA during the trim process got on my nerves very quickly.
The Frankford Arsenal case prep station is on my list to get.
