I'm super happy with the Maze 2. I don't know if you saw my post but aparently theres a new version that every one is calling the "upgrade". Supposedly the 1/2" versions are now usually this unit, maybe consider asking about it.

Also a word of advice, use good hose. I found (by burning a 1.33) that although the four corner stud mount is probably the best, it's weakness is you can leverage / rock the waterblock easily with stiff 1/2" hose. Get some silicon if you plan on the 1/2" route.
