I have had good luck buying from johnny's and burpee for different things, but if you want more than fairly standard pepper types u may need to look elsewhere
You might check out Tradewinds Fruit. They sell a wide variety of different seeds, including peppers. I have had good results with their pepper seeds in the past.

A friend recommended this site to me however they have been intermittently shutting down the site due to an overwhelming amount of orders. So it's not a reliable site for me to order seats from right now

Update to my previous post. They actually just arrived today, several days ahead of the estimate. Granted, it still took a while, but a lot less than I expected.
Ive put in 2 orders this year with Baker Creek aka Rare Seeds. No issues at all. Got my collards and kale started now. Free shipping, good selection and everything i ever ordered grew true.
