I bought my X3 from Grizzly for the following reasons.
1.) I've been very satisfied with everything I've purchased from them in the past
2.) My past experiences with Chinese manufactured tools have been hit or miss and I won't be surprised if I have an issue. Grizzly stands behind what they sell 100% and has the infrastructure (repair shop, parts dept., etc.) to make things right.
3.) I couldn't get either of the Connecticut Harbor Freight stores to let me use the 20% off coupon (after speaking with the managers) so the HF price was essentially the same.
4.) Though HF has made good on some of the issues I've had with purchases from them in the past. I had to wait a looooooong time for them to do so.
5.) Grizzly has put real money into providing good spec. sheets and a "real" manual (in English), so I'm confident that I know exactly what I'll be getting.
That's my take on it.... Was tempted to drive down to CT and save $250 at HF, but they were not loosey goosey with the coupon and the mill is a "special order" for them, so it didn't qualify for the 20%.
Grizzly had the mill delivered four days after I ordered it.
