AC110 or fx5 I would say. If you want canister then go with some of the smaller fluvals that are more in your price range. a 405 would look nice on a 125.

IME the magnums require frequent cleaning to keep them from loosing flow, this is compared with other canister filters. Also shop around you should be able to pick up the magnumfor 20-30 bucks less then posted in those links.
