well with the powersupply i meant a DC one i was forgetfull and forgot to say that though
would 5 inch long heaters be too long? i was thinking something around 3-5" long, the 5 inch ones seemed perfect as that could do up to 200W a piece so a single one would be enough but i was planing on going for 2 in parallell for a max power output of 400W.

mabe ill test my friend novashine's SP-94 with a 400W heatload and see how it fares since he is also going the way of watercooling.

also is it a bad idea to get used thermometers? like a used Fluke 2190A?
as a new one costs around $395 it seemed like a good one as i only need a resoloution of about 0.1°c which is all i need, it also takes pretty much any type of thermocouple.

why would getting RTD's be better? they seem to be waaay too expensive for me as the cheapest RTD elements are $45 according to omega.com

any good places to get a used Fluke 2190A? it seems like what i need.

Thanks
