I couldn't agree more with what Chris has said. I sympathize with your desire for perfection, but you need to know how to pick your battles, and absolutely perfect collimation is a battle you're unlikely to win on a regular basis, and certainly (in my opinion at least) not necessary to give you viewing pleasure, particularly with an ebay laser collimator (which is my chosen tool). If your stars are oval shapes then you're probably being a little too lax, but I think only the most skilled and experienced observer would perhaps be able to tell the difference between a scope with 100% accurate collimation and one that's very close but not quite perfect. Luka's link on how to collimate your collimator is very good, although in my experience collimating your collimator is much harder than collimating the scope itself.
