I share your interest in the Vector, but have been put off by the cost and lack of easy availability in the UK. In all probability I will get hold of one at some time, because I really like AC format razors, and it does look like a good design.
Regarding the ATT option, I also have one of their DEs (the R1) and have never been impressed by it. It's ok, but no more than that, and I believe could have been a lot better in terms of looks and performance, especially at that price. However, the aluminium ATT SE1 I have is a fantastic razor and probably the one I have used most over the last year or so. It can bite, but once mastered gives a close and very comfortable shave in a short time. Also, I like the relatively light weight and look of the anodised finish.
