The hornady has a trimmer, so I think comparison is unfair...
It really comes down to how much mony you're willing to fetch and wether or not you need a trimmer. Need I mention there aren't that many trimmers that are set up vertically? Future will tell (or already told) wether or not it is a desirable design since it is a relatively new product (I also know of trimmers that adapt to your drill press, but you need a decent quality drill press, unlike the one I have on hand)
I'll be happy to read what others have to say, I'm about to order the Hornady unit
