I hate to say it, but don't get the RK I.... Although it is a GREAT amp, you'll probably eventually want the RKII because it'll kill you not to have it.... Trust me, I know!! And yes, the cleans are "that" much better and worth it to get the RKII.
I'd just order it, you've waited this long, what's another 2 months? It'll be worth the wait..... Or you could get out the areal phone book and start calling around to Boogie dealers within driving distance. I've seen one RK II on ebay, you may keep watching Ebay too.
