Any opinions on this FX unit from Rocktron ?

Need it for Mod/Dly/Verb with a Marshall JMP-1 and Peavey Rockmaster. Will also go for a Rocktron MidiMate footswitch.

I heard about some reliability issues and freezing.
My other choice is a TC G Major 2, which is not so user friendly and a bit pricey.
Opinions please.

The Xpression is the best unit in the price range, definitely over the G-Major.

However, the older Replifex is even better. They go for around $200 if you look aroun eBay & craigslist.
