All, actually, the tax rate for both Washington state Rocklers is 10%. And the same for Woodcraft.
I work hard for my money and I expect the get the biggest bang for it I can. So when you consider that I dropped nearly $5k on Festools last year, by purchasing out of state, I essentially bought my TS55 with my savings. If states won't compete for my tax money, that's their issue.
And I still do buy from the local dealers, but really only for consumables or if I need something quickly.
Unfortunately I have yet to find a dealer that can surpass my knowledge during the demonstrations they put on from the knowledge base found here. Kind of sad when I can strip down a domino quicker than the store employee.
Shon, regarding dealers, especially being on the west coast, check out Japanwoodworkers.com. Best dealers I have had so far. And they do a real good job of packing your tools for shipping. I have had other dealers, some even mentioned here, blow off my request. So find one that you are comfortable with.
