Ya got to be careful just who you are buying from and if the warranty will be valid. Especially on Ebay or any online auction. It may not have a valid USA warranty. Buyer beware.

That you have to factor into the price. Good to be repair conscious when factoring the price. Also, if unwarrantied, good to have a friendly audio repair shop nearby who will work with you on the repair price.

Refurbs? You can save a bundle, but you better do your research on what you want to buy, the manufacturer and the seller. You could get stuck with something unrepairable (cost $ wise) and have a piece of junk---or an anchor laying around the house.
