Assuming you're driving nothing better than JBL's
And not running an amp
And looking more for power
And want to keep it under 150 USD...
Go for a 2001-2004 model range of the Pioneer VSX D810, 811, 812, 813 or 814 series. Reliable as hell, great power, good number of inputs and not a wallet buster.
I own the 812 and am looking to upgrade fairly soon since I bought better speakers. Though maybe I'll go for an amp first....
