I have the G1182-Z, and really like the machine. Got it used almost a year ago. Good solid feel, relatively quiet, smooth, easy to set up and adjust. The spring was shot on the blade guard when i got it--easy repair and parts were available from Grizzly. Shipping time and cost were actually quite reasonable coming from the "manufacturer"--not normally the case for replacement parts.
Coincidently, the 1182 replaced a variable speed Delta benchtop--lighter unit than the 37-190 looks like. It was an okay machine, but not in the same class.
