what hang on the back skimmer should I go with

I am just wondering can any of you tell me your thoughts on what is the best hang on the back skimmer? I am not looking to spend ALOT of money on it as at some point in the next year or so I am looking to drill my tank and put a sump under it. As for right now that is not possible so hang on is the way I have to go. So any help at well would be muchly appreciated. Oh yeah I live in calgary don't want to spend out my a$$ for shipping so would like to stay in calgary or at most canadian sites.

Thanks Everyone.
