It looks like at least the Tribute G&L series has taken a bump in price by $100, as L2000 Tributes that were normally going for $559 are now going for over $679 at most of the same retailers.
A used one just sold on ebay for $399, which is a bargain, IMO. These are the best budget production basses I've ever played for under $500, but that price has now apparently changed. If you can still find a retailer out there selling a new one or NOS for the old price, I'd snatch one up. Adirondack still has a published price of $559 with free shipping.
