I've not been in the market for one in like 11-12 years. Back then, they were selling for what he's asking new from Dart. But, I imagine they're asking more these days. I wanna say that my IE was ~$2k, back then, but that's before the machine work, which was also quite a bit. If I were to do it over again, I might just buy a complete motor. Good luck with your build, man.
