They are good for the money. Very versatile and a good sound. I would wait for a good deal though. I've seen them go as low as $40. However a lot of people still list then at like $60+.
You can get them pretty easily for about $50; very good sound for the money. Also be sure to use a power supply as they go through batteries like you wouldn't believe.
I got one for $40. I like it. The tape and modulation delays sound great. The looper mode is a little too rudimentary, but the other delay modes are musical and useful.
