Give me a museum and I'll fill it. (Picasso) Give me a forum ...
We are bombarded with more-than-weekly direct mail pieces from multiple window replacement companies. What that tells me is that the business is very, very, profitable. Lots of good advice here, including not buying from door-to-door salesmen, but in the end if you decide to get serious about this, I would start with a price that is 60-70% of the first offers and be sure to get more than one offer. When they object, thank them for their time and tell them you'll think about it. Then wait. Someone will call with a much better offer.
Re guarantee, a guarantee by the installation company is worthless. Look for a guarantee from the window manufacturer and read it very carefully, especially the "Exclusions" section. Check all the obvious places, BBB, the municipal building permit authorities, state attorney general consumer affairs, etc.
