Looking to buy a standard sliding patio door....quotes from Milgard, Window World, and Pella for vinyl sliders. See Lowes has ThermaStar Pella slider for reasonable price. Reviews on the ThermaStar are NOT GOOD. I'm confused...what do I need to look for in finding a good patio door? Not very excited to spend $2k for a patio door...whats are good price for value options to look at?

I've had a bad sliding door in my last house (not sure of brand, builder grade something) and so I know the woes...but I also am not bothered with the aesthetics of white vinyl so I don't need to pay for high end looks....I really just need good efficiency and long lasting mechanics!!!
