Where to get a window regulator Lonestar

[Yauchout]

Do any of you know where to get a power window regulator for an international Lonestar/ProStar other than the dealership. they want a pretty penny for that thing you'd swear it was made out of gold. my window stops about halfway up and starts making a popping noise I'm assuming it's the window regulator. I haven't pulled the door panel yet The power window motors only about a year old
