Oh, alright, I'd be able to afford that much for sure, especially if it's good.

You could even go cheaper than $30. I think that's how much the AC and mini canister cost.

Sponge filters are good for biofiltration, once they mature,not so good for water circulation.

I was thinking a canister filter? Mine worked for a long time, but it's making horrible noises now and just it's so efficient, plus it's the one that came with the tank. Any recommendations?

I would consider a sponge filter for your tank.

How important is water circulation in this case?

I think water circulation is very important for oxygen content and exchange of co2. In a 20 gallon you might be ok with a large sponge filter. I like hob for that size tank. Maximum oxygen level is important to support good bacteria.

I agree, circulation is very important for proper filtration. HOBs aren't all that great with circulation. Better than sponge filters I suppose.

But the plants provide oxygen in either case, right? And with a power head the water gets sucked into it a little, I heard.

Power heads definitely improve circulation.
