Even if equipment in the USA may look way cheaper at a first glance, beware of the charges you got to pay at the customs and the additional costs arising out of paying with an international money order! You often have to add some 25% to the price before the goods are here. Typically, goods at online auctions are some 15-35% cheaper than in stores.

Online auctions are a thrill. Ok, granted, I never have been into auctions before; thought it was something for bored folks with lots of money to spend on things they didn't really wanted nor needed in the first place.
The internet has changed my mind - now I know I need things.
So far, my experiences as a buyer has mostly been ok (except for a lady who got away with 60 DM without ever shipping the goods). As a seller I wish I sometimes never had thought about putting the goods for sale in the first place; it can happen that you get very little to nothing for the stuff and then you might be bound to sell it anyway (this is the case on alando, on eBay you can put up a "reserved price" and if it's not met, you're not bound to sell). Anyways...
What's the price difference between US online auctions and buying the stuff regularly in Europe?
I can't speak for the whole of Europe here nor of all of the online auctions in the States. It looks though like it's normally between 20-40% cheaper in the USA - before any taxes, shipping, insurance and other charges have been added.
