Have had the Grizzly G0619 mill for several years and have been pleased with the purchase for several reasons. The price (at that time) was slightly better than now but it still offers a pretty decent mix of range in X and Z axis needs - wish that Y-axis had a little more to offer but that's what it is. Have resisted the urge to turn it into a CNC version mostly because I already have that covered but rigidity wise, it would be an interesting package to setup that way. Grizzly sells the kits at higher than normal prices but it's pretty much a "bolt on" arrangement so not a lot of re-engineering to get it to work. I did add a decent DRO and that has made this small mill a great "bridge" for drill press work, light milling, angular setups that are pretty easy to re-set from and with the R-8 spindle and variable speed setup for the motor, it's very adaptable to a lot of tasks. The super low speed with the instant reverse actually works very well for tapping. Finding the right vise for the table is a bit of a test as the table width (in Y) is short and the placement of the vise is limited. You don't have to settle for what Grizzly offers in vises - there are others that are far more practical on this machine.
I would probably buy this again if it craps out beyond repair but that's mostly because I'm not relying on it as the "be-all / end-all" machine in the shop. It's a great "bridge tool" for the money. Thanks.
