THIS looks like a good price for these, but I don't need 5 of them. If someone can tell me if this is an OK brand, I might buy them and sell the surplus cheap. I only want one of them, so if you're interested, let me know by PM.
Any reason you want that model instead of a Belkin?
Large boxes are expensive. Fedex ground can save a few bucks over USPS and UPS for such stuff, but your mileage may vary.
In comparison, LTL truck freight can be a bargain, if you do it right.
