Numbers were on my side and still I failed
...
Nevermind!

I'd like to be able to afford the Iwaki but at £165($250+US!) it's too much, the Eheim was too much @ £45!. I'll wait until I find a way of getting the valves down pat then mod it. if I could gaurentee a good cooling increase over the 1250(modded) I'd save for one, but getting it in a case is daunting as well. I'll just have to wait and pray a cheap one comes my way...
