I have the old Electribe sampler (the green one), and it does alright, bit too much midrange, but through an EQ pedal and some decent reverb and compression it does fine for what I do.

My friend has the RS7000 and it's pretty awesome. I'm looking to upgrade soon and I'm wondering if I should throw down the extra $500 or so for the Yamaha or just get the new Korg.
