power windows = one of the best mods i did
its so handy pulling up to lights when there is someone u know on the other side and just winding down the window.
or.. getting fresh air in the car by window down a few windows rather then 1.
power windows can be costly. as the motors tend to go for a lot at both wreckers and new.
if you're dead set about keeping the manual window winders, then i'd swap bits and peices between the ghia door trims and some gli ones :)
