Looks like insects and uncertainty of what you actually get are two major issues, so I'll stick to growing from seed for now.
I ordered from CCN last year, and have already done so for the coming season. I had no problems with nasties when the plants were opened. They have a good reputation on this site. BakersPeppers, a member here, is also selling plants - you might want to PM him.
wow purple bhuts ...i would like to see pictures of them
C'mon now! Germinating seeds is half the fun/frustration of growing!
