I've enjoyed mine since 1992. Picked up a second one even (buddy of mine was liquidating during divorce).
To be fair, however, I've never loaded with anything else.
Universal shell holders (I have LS for big bore set up on one, S on the other). I can reverse the LS jaws if I ever need small.
"Floating dies" that pop in and out in seconds, using cross bolt die lock rings that are relatively inexpensive ($47 for a dozen at Sinclair), and every die of mine has its lock ring secured onto it precisely where I need it to be.
Priming function works really well also (I use a Sinclair hand-held tool for standard cartridges, but for my big bores, I just use the CO-AX: pretty easy to feel the appropriate seating depth).
No complaints whatsoever. Of course, the purchase price for both of mine, combined, was less than what they are now going for.
