If I were you, I'd check out so called "vintage" receivers from the late 70s (or early, early 80s)...you know...the giant silver things from Yamaha, Pioneer, or Luxman. I think that would be your best bet for $150 (some of the nice ones cost close to $1000 back in the late 70s). I'm sure you could find a used audio shop (or even a repair shop) selling some. They were built much much better than most of the recievers in the 80s and 90s (even the ones made by the same companies), they sound much better too, and many are rated 60-100wpc. As an extra bonus, they usually have good analog tuners and phono preamps built in. If you prefer to look for something newer and more modern, try to find something by NAD, Onkyo, Harmon-Kardon, Rotel, Marantz, NAD, Luxman, or Yamamha...they sound better and they're usually built much better than the mass market Sony, Pioneer, Kenwood, Technics, etc (though there are exceptions). I have a 30wpc Onkyo receiver that I purchased in 1983 and my brother is still using it. I replaced it with a *bigger* Pioneer back in 1989 or 1990 and that reciever died in three or four years.
