Im tryin to decide on a pump that is cheap, reliable and something i dont have to order off the net for my watercooling system. Im lookin for it to be about 250 gallons or so, is this to much for 3/8 tubing? anyways here are some links ive found: is this a good choice?

I dont know yet, i dont have it set up yet, just gettin ideas (i can get a block machined for basically free at school - it helps to be good friends with the machine shop teacher who got a new $50,000 CNC machine this year!!!)
I think i would like an inline system though

Ok.. while I am sure you can mod the Danner pumps to run inline, I don't recommend it.

Basically, submerged pumps are designed to be cooled by the water (weird though eh? ;)). When they are run inline, the water doesn't cool it off anymore, thus the pump running REALLY hot and reducing life.

On the site, it says that model 2 is fully submersible and has inline capabilitys. Could i put a fan on it to cool it down? Which is better in your opinion, inline or sub.?

I stand corrected, I was reading model 1 for all of them.

Yes, then you should be fine running it inline.

I like inline better - uses less space, doesn't heat the water up (as much).

Is 250 gph too much for 3/8" tubing? I know i should have gone half, but we had a bunch of 3/8 brass fittings layin around, so....im cheap :)
Thanks sneaky, just wanted to make sure im gettin a good pump

I like my maxijets... cheap, quiet, reliable. They must be used in a reservoir, but no biggie. You can use a plastic electrical box from home depot as a reservoir. Just cut the appropriate holes, put the cord and barbs through them, and seal them up with superglue. Lots of it. And these boxes can be bolted down inside your case if you so desire.

3/8" tubing has an inside diameter of 3/8", where as 3/8" barbs have an inside diameter of 1/4". Get 1/2" fittings for your pump, and stretch the tubing over it. This should increase your flow and possibly keep the pump cooler

Via pumps you might find locally.

I have used a danner 5 on a moderatly restrictive system. The danner leaked at the seal. Easy fix, all i did was smear silcon around the manifold. In short... seal the manifold.

take advantage of the danner uses. use 1/2" lines.
