well i finaly got my new canister filter.i ordered a via aqua 750.so far it's been running for about a week and i like it.it looks very similar to the ehiem professionale series of filters in design except no self priming pump.i chose the via aqua for the high flow rate 316 gph.and it only cost 70 bucks from bigal's.my only complaint was it didn't really come with any media.overall so far itr seems to be a great low cost alternitave to the ehiem filters.as time progresses i will post any updates here
