What protein skimmer brand is the most quiet sounding ?

[reef93]

I am using a ASM G3 skimmer for my 75 gallon and 40 gallon sump, it works perfect and skims very well. The only problem is, the noise from the returning pipe is like having a constant waterfall in my bedroom. I don't mind in the summer time, because the humming sound from the air conditioner is louder than the sound of water. But now the weather is getting cooler, I have a hard time to fall to sleep at night now that the air conditioner is turned off. I am looking for a skimmer that is not costing too much money and it has to be quiet. I perfer to ask someone from this forum first before I spend money on something I may regret later. I prefer the foot print is no bigger than my G3 right now.
