I am considering upgrading my band saw guides to the ball bearing type. Since the lower guide recently broke I'm considering an up grade from either Carter Products or Sawblade.com. I've seen posts where a number of SMC members have upgraded to Carter guides, but I ran across Sawblade.com while searching. Has anyone ordered or have experience with Sawblade.com? They don't identify a business location on their web site. Sawmill.com has a kit that will fit my Delta 14" band saw. I have never done business with this company and would like some references before I decide whether to make a purchase from them.
