Randy, I don't have have experience with the Grizzly machine, or others obviously, cause I'm the one that posted in that thread. The Grizzly machine is a good price but I'd be concerned about the cutter it uses. It says it's a 18T carbide cutter. I would check to see if that cutter is proprietary or not & if anyone else other than Grizzly sells replacements. But maybe something else would work as a replacement. It would suck to buy the machine & if later Grizzly discontinued it & parts then to be stuck without being able to get a replacement. Here's the cutter for the Grizzly, pretty pricey,
$54
I went with the one I did cause others sell the same looking machine so I figured I may be able to get parts if ever needed. Not to concerned about parts really but the main I reason I went with the one I did is cause the cutter uses 6 SPU inserts which is commonly available & cheap on ebay.
These machines are called Chamferring & Deburring machines, well mine is anyway. I have plenty of Nogas like the hand deburring tool you linked too. But this machine is a bit different. If you have a raised burr on multiple sides of the part you're running through it, you either still have to deburr all the sides first with a file or tool, or run the part through the machine twice, once to knock off the burrs, then a second time to get a nice bevel. If you have a burr, it will cause the chamferr to be uneven. So really, I use my machine to put chamferrs on a part which is what I wanted it for, not necessarily for just deburring.
This is the chamferr I get with my machine only set to .5, it can go all the way up to 3 which is probably & really heavy chamferr.
