I'm not a huge fan of sriracha generally. I found an economy size bottle (tub is more like it) of Frank's Red Hot at wal-mart. I am officially in heaven. Best thing in the world: canned chicken, cream cheese, a little bbq sauce, and a lot of franks. It's this buffalo chicken dip that just... oh man, i'm hungry just thinking about it.
For baked potatoes, I like 100% Pain.
There's a salsa (not a hot sauce, but still) called Tat's that uses the ghost chili- that stuff is incredible- http://www.tatsoriginal.com/products.html the one at the bottom.
