Since Guitar Center's having a great promotion right now(no payments or interest till '08), I've been eyeing a GK700RBII. I'm playing through an old Crate BT-350 that's seen better days. I'll have no problem paying the amp off in a few months but with Christmas around the corner, I'm feeling a bit selfish at the thought of buying myself a present. As far as gifts go, the kids are taken care of and so's the wife. Should I or shouldn't I?
