WAR-TOYS

Everything said about Monkey Depot is true about War-Toys as well. You will find them cheaper on some things, higher on others, but it pretty much will balance out overall. Their service is just outstanding. You can order something on Monday and a lot of times have it on Wednesday with regular old USPS.
COTSWOLD COLLECTIBLES

I have personally been using Cotswold Collectibles off and on since about 1990. They don't ship quite as fast as Monkey Depot or War-Toys, but I have always found them to be reliable and they have some things that nobody else has, especially if you are into vintage Joe stuff. And they are just really great people to work with. If you are a regular customer, you can get their catalog in the mail. It is one piece of mail I look forward to each month.
TOY ANXIETY

Great Prices, Great Selection - they carry some things that others do not, more action figures in other scales (Simpsons, Batman, etc.) They also ship really fast, so you can have your stuff pretty dog-gone quick.
