I have read a great deal of postings here about GFS for parts upgrades (I am beginning the upgrade process on my STL50), but have also seen several positive reviews for Bezdez on ebay who apparently offers similar quality parts for less and lower s/h costs. Anyone have experience with BOTH and can comment? I can get ss saddles and roller trees from Bezdez for $15 incl s/h and the same at GFS would be $25. I am obviously leaning toward Bezdez, but wanted to see if anyone had bought upgrade parts from GFS, then found Bezdez for their next project and found the quality to be the same. Thanks!
