I really don't think that Thermodynamx and Lean System 7 are bad products. A bit underdosed, maybe, but with price not being considered I really don't think that they're terrible. They are a little more expensive than the rest for what you get, though.
Like weeviekins said,
Tight is a good product. Other good ones are
Ergopharm's
Ergolean MC and the tried-and-true ephedrine-caffeine stack. Avant's new H.E.A.T. is good as well.
Honestly, of all that are readily available, you can't beat ephedrine HCl (product called Vasopro) and
caffeine (
Prolab has very cheap
caffeine tablets). The price can't be beat, either.
