My opinion is if you have the space and the money to set up a really nice external canister powered water feature you will save yourself a lot of headaches tearing the tank apart to work on the pump if it fails.
Eheim are some of the best on the market. To be frank, you probably don't need one that good. You could do with a much cheaper and less powerful one for a water feature. Those are made to filter a lot more water, and you will probably be filtering less than 5 gallons.
A fluval 105 would be more than enough power for a water feature, and is about $40 less.
ViaAqua are much cheaper than the fluvals but I am not familiar with the brand either: http://www.marinedepot.com/ps_AquariumPage~PageAli as~filters_viaaqua_canister_external.html
There is also this mini canister (not familiar with the brand however) that could be used if you use a background to hide the hoses, or connect clear tubes to them. Something to think about. http://www.marinedepot.com/ps_AquariumPage~PageAli as~filters_tom_aquatics_oscar_enterprises_rapids_m ini_canister_filter_c_80.html
Eheim or fluval would be better if you may like to do a saltwater aquarium later down the road. But if this is all you are going to use it on you could go with cheaper.
