For $200, the TKC is absolutely hard to beat. Definitely gets my vote.
The Addicts share much of their edge geometry with the Artifex....both made by Lamson. However, unless you are rather in tune to the performance of a really thin edged gyuto....either will be a great improvement over something like Wusthof or Henckel or other some such western chef's knife. YMMV, but that's my opinion.
Otherwise, the TKC, when back in stock, would get my first vote.
If you want to go out on a limb, pick up the Goko....http://www.chefknivestogo.com/gokogyuto240mm.html
It's stainless clad carbon, so not too much of a maintenance issue.
The Masakage Yuki is really nice too:http://www.chefknivestogo.com/mayugy24.html
