I just won a Palio Cutter with the Kentucky Fire Cured on Cigar Bid for $7 last night.  I have used the American ones before but never owned them.  My Zikar started to stick.  I was going to send it back, but ended up losing it.  The palio will probably be a back up.   
I ended up getting a Cuban Crafters Perfect Cutter Large Ring in stainless steel a few months back.  It is solid, heavy  and takes just a sliver off the foot.
