Loopers?

[HaykEsa]

I've been intrested in a looper, something to practice with, nothing huge. I have a few options, just wondered which you would recommend.

Jamman:

Boss:

Or should I hold out for the new fancy Line 6:

Right now I'm leaning towards line 6, because from what I've seen, all their stuff has a ton of incredible features. Any opinions are welcome!

I have the Boss RC-2. Easy to use - You can enhance it's capabilities by adding an external pedal like the RS-6. It has almost all of the features that the RC-20XL has. (and the price is alot nicer too!)
