What preamp and speakers are you using?
If you're patient, you might find a used Outlaw in your price range, but if you want something now, look at Parasound and Rotel. They offer a great bang for the buck. The 140 watt Parasound HCA-1205A might not reach your 150 mark, but Parasound amps are overachievers with their massive power supplies and high current design.
I don't know anything about Emotiva.
