Hos,
If you want some serious heat, combine the classic recipe combo of frank's red hot and butter with some thai peppers. Thai peppers are great for this because they bring a lot of heat while not altering the flavor of the base wing sauce. Simply make your wing sauce and throw it in a blender with the whole peppers (minus stems of course). Thai peppers should not be hard to find and should be available at the grocery store, or maybe an upscale market like a whole foods.
Heat comparison:
jalapeno - 3,500-4,500
serrano - 7,000-25,000
thai pepper - 50,000-100,000
habanero - 200,000-300,000
Now, if you want to kick this recipe up one more notch, roast the chilis over a nice smokey wood like a mesqiute or hickory, then blend. I made a wing sauce like this once and it gave it a smokey firey kick that I'll never forget.
Also, chicken tenderloins are perfectly acceptable subsitutes for wings/drums. All white meat, cook up quick, and can be cut into nice bite sized chinks and drenched in sauce. A high meat/sauce ratio is key!
Side note: did you ever have the wings at DJ's in Tucson while they were still around? Some of the best wings I've ever had, and the suicide were so hot, that I could not eat more than one. They've been closed for about 10 years now which is highly unfortunate.
