Personally, I'm not that big a fan of Red Sea Skimmers, but they are decent. I won't say you can't do better, but it will at least work. Some of the classic skimmers may need some minor mods to get them just right.
As for Ebay and the almost required use of PayPal. I simply will not buy that way. To me this is automatic disqualification. However, others have gone this route, and been happy. I see the big problem being, what do you do when something goes wrong with the sale or product?
