Bobster,
That's what I thought; discontinued. It's a shame. I like the look of them better than the 300's. Plus, in my opinion, I think that the 5-piece maple/walnut neck would be stronger/more stable.

I bought my first ATK 700 on 3/17/2010, new-off-the-rack, from an independent music store in Colorado. (Pic on left) It's a bit darker blue than I normally see on these. Kind of obscures the maple top, but I like it all the same. The balance, feel, playability, and tone are (to me) outstanding.
I was so impressed with it, in fact, that I just had to get another one. So, on 3/20/2010 I bought one from forum member pathdoc2. (Pic on right) This one looks to be a lighter blue, like I see most often. I don't have it yet, FedEx should be dropping it off tomorrow. Based on other players reviews, as well as the experience with my first one, I'm confident this will be a fine instrument also.
