So I talked to a few members on the forum and ended up going the 65mm steel pulley route from a company in Poland that was recommended to me. Did some research and people on MBWorld and here spoke highly of them.
Not only is that pulley a phenomenal price (Great exchange rate between Polish Zloty and Dollar), it's also made extremely well. Hardened steel with titanium springs.
Have never had an issue with belt slip..if that was of concern, could always get a belt wrap kit from Needswings but I didn't see the need for myself. Feel free to PM me with contact info for these guys in Poland if you are interested.
