They have regular discounts on packaged items. I got my DD5 pump and TDX for like 105.00 i think....the pump alone is 89.00 and the TDX is usually around 50.00 w/ the accelerator nozzles. Add that to a 42.99 -> BXII and you got a darn good start to a nice setup.
**BTW- I RMA'd three of those BigwaterSE's when they first came out aloooong time ago. The pump size is completely to small for even the 10cm tubing they use. Just adding a gpu block into the system, the pump froze on start up trying to cycle the bubbles out. All three pumps....same story. If you must go Tt, look for the larger system w/ 2 radiators. Those feature an upgraded pump, almost 3x the flow rate of the last version. I think the radiators Tt uses are really quite good, I was able to acheive a 26c idle on my P4 630j @ 3.9ghz, and a 46c load. I dont think thats bad at all for the generally generic quality of the parts.
