Thanks for all the advice!
I didn't end up getting a heater, but a friend gave me some planting cells and nice Amish dirt he likes, so I'm at it again with some old seeds and some new seeds.
In answer to some of the questions, almost all of the seeds are from White Hot Peppers. I put all of the seeds I may have toasted in the last attempt in this dirt, along with some new seeds, which I didn't treat with H2O2. If this setup (described below) doesn't work, I'll break down and get a real germinating setup, or just buy plants when its that time of year...
I took a coffee tin and supported a 6-cell planter on its rim, filled with some good, loose starting mix, and placed the seeds on top. I put a little water in the bottom of the can, to keep the air humid, and moistened the soil with mists of water. I then made copper wire hoops and covered the thing with plastic wrap, then placed it under a lamp. Below is an ok picture of the contraption. Any suggestions? Should this work?
