I bought the GSC-2 when I was looking for a good deal on a G-Force, but ended up with a G-System instead. Check the specs in the link and if you're interested I'll make you a good deal on mine. Never been used. http://www.glab.com.pl/gsc-3_en
Yeah, pretty much all MIDI pedals are comparable. It really comes down to what features you want. The MIDIMate is popular because it can be set up so that the bottom row changes presets while the top row can switch on/off effects within a preset. Many of the cheap ones wont do that.
I use rocktron MIDI mate. Perfect size. I don't really like the rubber plastic buttons but the lay out fits my deal nice. Always found the others to big. Which would not be a issue if everything is racked
YOU CAN GET AN ADA MIDI FOOT CONTROLLER ON EBAY FOR AROUND 100 BUCKS. I KNOW THEY ARE OLD BUT THAT IS ALL I HAVE EVER USED. THEY ARE RELIABLE AND THE BUTTONS ARE BIG, SO WHEN YOUR DRUNK YOU HAVE A BIG TARGET.
