Decent cheap filtration for 125- suggestions?

Thanks, MGamer. While I don't think the water-bottle method is going to be adequate for my tank, it actually is a pretty good idea about using the main tank as the sump and putting the filter above it; that way I don't have to worry about building siphoned overflow boxes, since I can just stick some bulkheads and internal overflows in the filter.
 
how come? it works thats all that matters. heck if i had a attic i would put all my filters there lol

Cause I would want something sturdier, and instead of running a million containers, with questionable flow, I would just spend the extra time and build Sploke's link. But if you run your fishroom in your garage, couldnt you use the rafters the same as an attic?
