I wouldn't call the aquaclear design ingenious heh...
Sure it is! Its amazing how they put one filter media on top of another! And with this design, they are able to stack them 3 high! lol
Seriously, I do like my AC110s. Also, I agree with clockwork on his comments about the Rena's. I have an XP4. I like mine since I got it basically new for about half price, but it's a pain to re-prime after cleaning. I won't go as far to say they are a bad filter or are to be avoided, but they would be the bottom of the list for my recommendations.
Petsmart had their Fluval 205 for $90, not sure if the sale is still going on. But even so, its only a 40 gallon filter. I like to oversize my filtration by at least 2 times.
OP, have you looked for used? Maybe check Craigslist or at your LFS. One of the stores here for example has 2 Magnum 350s for $40 combined, a Magnum 250 for $20 and several HOB filters (AC50s, Emporer 400s, etc) for $15-$20 each refurbished. If you look at used, make sure you check them out closely (look for signs of wear on the impeller, magnet, etc). Also, if there are no cartridges or filter media, know that it will cost you at least another $10-$20 or more to get what you need.
Lastly, a lot of us prefer to run at least 2 filters on our tanks. With this set up, when its time to clean your filters, you do one at a time. You are able to maintain your bio with the second filter. Next change, change out the second filter. Another advantage of course is if you have trouble with one filter, your second one is still going while you repair or replace the first one.
Good luck!
