I started out with a Digitech RP100 and then moved up to the RP2000. Both had great effects and were very versatile. The amp modeling was lacking a little, but besides that, I really enjoyed playing with both of them. My cousin has my RP100 and I still enjoy messing with it whenever we get together an play. It was about 6-8 years ago when I got the RP100, so I'm sure they've improved some.
