I have the 2000 version of the APS external filter for about 10 months working perfectly.
I really can't understand why the complaints about the filter flow. The only reason would be if you are using the spray bar, the holes in it are really tiny and can get clogged easily. I never used the spray bar and the guppies can't swim up there. Here is a video of the flow of the filter with one major cleaning in 10 months time:

I might try it out when finance allows. It would be nice replacement to either an internal in my 30G or addition to my bigger tank. I've got the APS 2000 in a 330 litre tank and I absolutely have no complaints considering I've sand and my 7 inch poo machine(pleco) hasn't been able to destroy it. I don't siphon anything, just do a water change. So if if tetratecs combos are better, and I've read here a lot of members recommending them, I might give it a go. It will come in use one way or another.
