What Type Of Pump?

Been thinking of hooking up all my tanks to sponge filters and am debating buying two 60-100 gallon tetra whisper air pumps or a big commercial pump that will be hooked up to PVC. What would be best and any recommendations for the type of pump and where to get it.

Tanks:
1x 40g
2x 20g
1x 10 gallon (Maybe 2)

Thanks to those who help!

 

I use tetra whisper air pump

 

I use the tetra whisper air pump and run it 24/7 with no issues and love it

 

I have used this airpump for the last few weeks and I love it thus far. Quiet and inexpensive!!

 

I use a lot of AZOO air pumps, but they are louder than most others. JW Pet ones are pretty quiet, as are tetra whisper. Theirs a ton of air pumps on the market and pretty much all of them are decent. Also heard good things about Aquatop, but never tried them myself.
