yeah, I said about the pre fab ones, much easier and cleaner looking like you said. I do have one of the tru DIY ones, run like a champ( I don't think you can buy the kits from MJ Mods anymore, stopped making them, it is twopartsolutions now), it does occasionally spin the wrong direction, when I shut the pumps off, it broke the stopper like the second time I did this, so now I just stick my finger in to stop the impeller and it starts to spin in the right direction.
