It really depends on what kind of windows..I found that for solid wood windows with solid wood jams AND a "normal" window sill, that the prices are VERY high...also not many manuf. do them...<:-(
Then if you add anything special needs/wants like energy efficiency (low E) or dual pane with sound proofing specs, you are easily talking the MOON in price and the $20K+ is not out of range...
Have done EXTENSIVE shopping...and am still flabergasted!!!!
