i was searching the internet and one thing lead to another and i hit on Refining Fire Chiles. got to thinking, is this site listed in this post. i didn't find it in the list, so i then searched the forum and found a number of posts saying they purchased plants and were very happy with Jim's products. i didn't search further to see who purchased seeds, as there were a lot of hits - i did search the contents of this post and no hits(all i used was "fire" in the search).
habanero500 has an interesting post on scouville ratings of his tested supplied products, it's an interesting refresher if you haven't reviewed the post.
