I've got a zoom gfx 707, it shud b in your price range. It's got 32 preset effects, n you can customise any of them. The sounds pretty good, don't know if I'd use it to gig though, it's only got two pedals so to get to another sounds you have to tap through them all. But for pissin about its great. It can make your guit sound like an aeroplane, which is more of a novelty thing. And it has a Van Halen settin which is ****in heavy, you can hold a note for about 40 seconds just holdin it. It's really good for that two hand tappin. It's got all the other additions too, 6 sec recorder, built in drum machine, n a tuner( pretty standard for multi effects)
