Nah, I didn't have a bad experience, just the fact that awhile ago a lot of people recommended it and said Bob gave great, custom-tailored advice to people for tube selection for their individual amps, so for a very brief time I too recommended them and ordered a couple of pre-amp tubes and the bias probe/multimeter - but it didn't take me long to realize what a fucking joke "custom-tailored advice" is coming from a guy that sells exactly one brand. Basically, I just see absolutely no reason why anyone would want to buy from a site with an atrocious selection when you can buy from others with much better selection (and still staffed by awesome, friendly, knowledgeable and helpful dudes, esp. Doug's) - and it's not like anyone would say JJ's are the be-all end-all greatest tubes out there either!
And both Dougs and thetubestore.com definitely sell all variety of JJ's, btw - hell, I bought a pair of JJ 6L6's for my 5150 combo back in like '05
