I really want to get some STP on vinyl. Are the only three albums released on vinyl Core, Purple and Tiny Music? Does anyone know where any of these can be found at a somewhat reasonable price? Are there any plans for Atlantic to re-release these?

Those were the only full albums released, yes. A lot of the singles/promos came out on vinyl as well. Your best bet is usually eBay, however there is a great site called eil.com which specializes in imports and such. I've gotten a lot of cool STP vinyl from them over the years:

I wouldn't count on Atlantic to re-release the vinyl.

Thanks a lot for the info Matt.

Do you want to sell me any of it

gemm.com is another good site for vinyl.
