Read about it in one of the bigger wood magazines some time ago. They put the molds and features to the test. If you have actual meters to measure flatness for instance, the grizzly surface is not as flat as a Jet. It's not like that matters though as it's a difference in the thousands. If we are talking table saws for instance, you may recieve brass sleeves in a grizzly rather than ball bearings. Again, no problem unless you are using the machine all day every day. You may get a lesser motor in performance and quality as well, where as a jet will usually get you a high quality baldor motor, which again is no big deal unless you are using the machine all day every day. They say the first molds poured have the most slag and automatically go to the grizzly pile for contamination reasons. All these machines are using the same molds made at the same factories in Japan/China. You walk in a show room and you can instantly see they are the same but not at the same time. This is just what the magazine says and does not mean you shouldn't purchase grizzly. I have some grizzly tools. When it comes to price you can't beat it. Wood magazine gives them bonus points all the time because of price and because they know what the average user will use if for. Lets face it, grizzly is plenty good enough for any of us as none of us are producing factory flooring or factory furniture. So, I'm not really down talking Grizzly machines, if that's what you think..just throwing out some "magazine facts" about them to consider. I'll have to see if I can dig that out of the monster stacks of magazines in the barn some time. May have actually been Popular Mechanics now that I think of it. I know it wasn't about knocking a particular company, it was in answer to someones question as to why so many machines look the same but have such a broad price range, something like that. I know they had pictures of the tools, where they measured and disassembled everything, did tests on the metals and all sort of stuff...like Mythbusters I suppose. To me it's a lesson in you do actually get what you pay for, even though you may not need it all.
