Minnkota Windows - Any Info Appreciated

Any info. on your experience with Minnkota windows would be appreciated - particularly the quality of Minnkota's tilt turn units.

i just checked their website. minnkota double hungs in double pane only get a Ufactor of .30 . there are many other companies getting a 27 or lower; in fact some are as low as .25 .
you can get minnkota down to a .29 by adding lowE 366. i dont know who in their right mind woukd recommend lowE 366 in north dakota unless there is a desert i dont know about.
