Filtration suggestions for 125 gallon

Time to start geting down to the details on my plans for the new setup so I can get my shopping list together and start piecing it all together. The tank's previous owner was running two little HOT Magnums on it - which they did include when I bought it. The fish load they had was pretty minimal (I saw two small common goldfish and two small catfish - all under four inches each), so it worked for them, but if I have a 125 gallon tank I am going to have a 125 gallon tank (meaning more fish than that).
The two options I am debating now are:

1 - run the two HOTs and add a decent canister to supplement the HOTs (or the HOTs would supplement the canister, whichever way you want to look at it)

2 - shelve the HOTs all together (would make good back ups as that is what we are using on the other two tanks now, so if one were to fail we would have a back up - or if another tank were to show up on our doorstep looking for a new home ) and get two canisters .

Any thoughts? I am still undecided on what will be going into the tank besides Mr. Awesome (common pleco - currently 8-9 inches in length) but considering what a dirty boy he is I know I need good filtration regardless of who lives with him. I do know that I am leaning towards mostly smaller, less "dirty" types of fish on my list of maybe fishes.
In the past we've had RENA canisters, so I've been looking at those for this set up - any feedback on yay/nay for that?
If this were your tank, WWYD?

Has anyone had any experience with "Aquatop" filters?
I came across this on Amazon while comparison shopping some other canisters. Would likesly to two 400's vs one 500 so that there is a back up should one fail.

I liked the marineland C series that I got recently, they make one for up to 150 gallons, the C-530

The listed price is high, that's the MSRP.

Definitely go with fill canister filtration and shelve the little stuff.

Total years fish keeping experience: 7 months, can't start counting in years for a while yet.

For a 125, I'd go with a canister, not HOB's. For canisters, Eheim, Rena and Fluval are top picks. The Aquatop looks good but I have no information about performance and reliability and we rarely need UV sterilizers.

Father Knows Best but Abbey knows everything! I once knew everything, then I asked one question.

I wasn't looking at the UV as the selling point on that guy - they actually have a non-uv equipped version as well. I am thinking I'll order one to try (for the price, even if it doesn't work I'm not out much) - had an unexpected vet bill come up last night (not sure what it's going to cost when all is said and done just yet) so I'm having to take a little of what I thought was "play/fun" money out of my tank fund. I want to get the tank up and running so I can start cycling and will just upgrade the filter later if it turns out this little guy isn't all he's cracked up to be.
