Coltrane,
I have not seen this one, but a friend has a very fancy, record flattener that has it's own heating elements and sophisticated time/temperature controller to gradually ramp the heat up and down and takes about 8 hours to go through one full cycle. Looks like a round waffle iron, isn't cheap, but it does typically work pretty well.
This looks like an interesting alternative for about 20% the price (with the heating pouch added.)
May look into it myself once I get out and start looking for used vinyl.
