Actuually, I want the 240 not the 270. I have a very nice 240 as it is but I like the handle of the Misono soooo much ....
Foo, for you I would recommend a 210 or a 240. you have to try them out but if you like the Masamoto VG then you can't really do alot better, for quality or price. I think I prefer the Misono handle ever so slightly but I have very large hands. Misono over masamoto is a large premium and the profile of the latter is superior, though the steel in the former is better (or at least more expensive).
Depending on what kind of work you do, I would also recommend a german chef's knife, or, if you must have Japanese, then a Deba. You won't want to risk your gyuto on anything too hard or large. Anything that requires a great deal of pressure to cut, even a large squash, could damage the knife.
The other brand to look at is Mac. roughly on par in quality with masamoto. Those two seem to be restaurant workhorses for what that's worth: good enough for intricate work, not so expensive that you cry if something happens to it.
