Had to make the decision myself a couple of years ago and chose the Delta.
As near as I could tell then, and have found no reason to say things have
changed, both machines perform their basic functions quite well.
I chose the Delta over the Performex because I consider the fixed drum head
design more stable, liked the versatility of the two speeds and, there is
the ability to add a 4" pneumatic drum on the machine. It is an amazingly
handing little option.
So, without taking anything away from the Performax, I've have no regrets
about the decision.
