manual windows would be kick ass, my switches are all jacked up. the swap would be real easy. i can get all the hardware from my local junk yard for less than $50. i will be doing that sometime when i get my tax return. do it yourself though, i work at a mechanic shop, i dont know what shops around you charge, but here in the city of atx i cost 2.5 hour per door worth of labor just to open the door panel, but no extra labor for replacing stuff. should only take 1 hour per side if you dont know what your doing. anyway that is my two cents. the reason i was saying manual windows would be great is if you ever submerged the car then your power windows would not work anyway, and with my driving record you cant be to careful.
