The Pioneer 1015 would certainly work for you, but it would cut into the money you saved by buying the JBL's refurb'd. If you like the 1015, you should get it, but you probably would not be able to tell the difference sound-wise between it and the other, lower priced options already mentioned.
BTW-The "100 Watt" rating for the JBL's is virtually meanless. Just don't push the amplifier beyond it's limit and it will be fine.
