I much prefer COMC because they do all the work, and you can buy and sell cards on site without taking delivery of them. I think they're much better for buyers than sportlots because their user interface is so much better, every submitted cards gets its own front and back scan (UD ePack cards could be stock photos however). Their cards are also mostly cross-posted to eBay so you get the advantage of eBay buyers without having to do any shipping.
