I've been very impressed with Squardon myself- just the other day, they called ME because I had filled out an order form incompletely! Now that's service!
I've also used Great Models Webstore. Good experiance, however they do things a little differently. They don't stock all their advertised items and get them from a distributor which can take longer. There are pro's and con's of this approach.
The good thing about both these online web stores is that they provide pictures and detials of each item. It's nearly as good as going to your local hobbyshop to browse!
