The 450 version has the very weak pump, the 750 versions are the better of the 2. Also, the one you listed was a single 120mm radiator, the one I have listed is a 240, similar in size to the H100.
Where are you buying from? Like you mentioned, price might be an issue...and if that is the case, you might wish to just consider a very good air cooler. I've never really been able to justify the H100 at it's price when the XSPC RS240 kits are very, very similar in cost but perform much better.
