Good Inexpensive Amp for Back Yard Speakers

Hi Y'all. 

Could use a bit of counsel. 

I need a decent, but quite inexpensive Amp to pump my circa 1990 Klipsch HS2 outdoor speakers on the back porch.  Need something with some decent wattage (not 20 watts!).  I'll run the amp out of one of the outputs from my pre-amp.  Given what I am running to it makes no sense to be spending much on an Amp.  I don't want to run it through my existing Amp for the living area because I need to be able to have separate volume controls for inside and outside.  When the house has quiet volume, I need to put some power behind the porch.  While I'm at it I will need the ability to hook up two speakers since I will run the in-walls in the dining room separately too.  I've been looking at used amps but just not finding much at a decent price.  I started looking at this Russound P75 amp for about $120 which looked good.  Then I started reading the reviews and they were quite uncomplimentary.  It tends to die or burn up after about 90 days.  Parasound looked like an option but the pricing was too high for what I will use it for.  Would appreciate some ideas from you Goners.

Thanks in advance.
