Best price for T5-Z

[Mosix]

As I was driving yesterday a small rattling noise started coming from my transmission in the first three gears and it gets quiet when in fourth. I am looking to buy a FMS M-7003-Z, Summit has them for $1150 and will price match so does anybody know someplace that has a better deal? Does anybody local buy T5 core transmissions or should I throw it on the scrap pile? Maybe on Craigslist as good used trans J/K Thanks
