I have the Block from Jewkes (don’t use it much) and he is really helpful but if you want the most up to date supplies to keep up I would use DD4H. I bought the SBE from DD4H and wish I didn’t waste money elsewhere. His wheels Work great and polishes are on point. Hope that helps.
 
I've got The Block from Jewkes. Drills done with the block are right on par with the SB Extreme, but the setup and use is WAY more tedious. I use the SB Extreme for drills now, but The Block is still an essential part of my process as I use it to test the drills ( see Lightnin Boy test )
