Rob, if you're thinking about a dehydrator, check out this one.
Excalibur

Before you visit their site, I'll warn you that their dehydrators are more expensive than those you'll find at Walmart. But they are well worth the investment.
I have a Wal-Mart version. Tried it a few times, then put it on the shelf, where it's collecting dust. Now I have 2 Excalibur dehydrators. The smallest one and the largest. Spending a little time on their web site will explain, better than I can, why they are a better value.
Anyway, regardless of which brand you buy, here's a tip. Set your dehydrator up outside, in a protected spot, to dry peppers/chiles. It's an understatement to say the aroma of drying peppers can be a little overpowering. (Don't ask me how I know. )
