Seattle resident (US Citizen) wants to buy a $900 keyboard amp of Canadian manufacture from Vancouver B.C. music store. How much it would REALLY cost after taxes and customs duties? Store couldn't tell me; getting busy signal from Border Information Service 800 number. GST - about 5%? Additional provincial tax for BC, and if so, how much? Additional customs duties? Would drive up from Seattle and buy in person. Is this insane, or should I just special-order via Seattle music store and save money (but not time?)

I buckled and bought a set of AKG k701 cans. They're currently hooked up directly to my Airport Express and sounding great, just lacking the final couple of decibels. Can anyone offer any advice on choosing a suitable headphone amplifier or, even better, suggest a recommendation (sub $500)?

I watched a documentary tonight about a music festival, and one of the guitar players had a totally awesome-o guitar amp, a little bitty one that he wore around his waist on a leather strap. It basically allowed him to do the wandering-guy-with-guitar routine, but with an electric. What's the best one of these to get, and where's the best place to get it?
