The 2011 has pretty much the same flow rate as the Zoomed Canister filter. I tried a used 2011, and was pretty disappointed because I thought the flow rate would be significantly better than Zoomed's
I'd opt for a 2232 if you can afford it. If you have a PetSmart nearby, you can find the lowest price you can on the internet, and see if they'll match it at the store. If you have some bad luck, they might say no, but most employees won't care and just give you the discount.
I have the 2234 on my 20 gallon tank and it rooocks. Maintenance is easy and flow rate is more than respectable
