On the cheaper side of things, Rocktron Intellifex are pretty simple to use..and sound good. I recently grabbed a Lexicon MPX 1 and it is a step up tonewise to the Rocktron, but it's far from easy lol. I just have a few fav presets and have fun with those. You can find the Intellifex and a Midi mate pedal for less than 200 usually.....The Intellifex does have the 8 voice chorus that makes it unique, and some players that have the big dogs(H8000, PCM 81, TC 2290) still keep an Intellifex around just for that feature.
