I run a Blue Line NS 1100 pump on my skimmer. Its quite nice. It will be louder than your T4 due to the fan, but I have it in my living room and I barely notice it (its not hidden in my stand or anything like that either). Its also nice that it is pressure rated and only uses 70W of power!
I got mine from Ocean Aquatics. MOPS.ca also carries a full line of BlueLine pumps.
