Mailist to discuss all issues regarding the Digitech GSP-2101 Guitar FX Processor

Hello, I've been a member here for a long time, though I've never 
posted before. I've recieved a lot of good information here and for 
that I'm grateful.

I'm thinking of selling my 2101 in favor of a Vox Tonelab, but am 
wondering at the going rate for the 2101's? What are these selling 
for?

Thanks.
E
