I have an Amana Radar Range downstairs in storage that still works fine.
I upgraded to a GE Advantium when one became available to me.
I'll go back to the Radar Range if the Advantium craps out.
I haven't used the halogen features much. The learning curve is more then I want to deal with and my regular oven serves my needs just fine.
I use the microwave to reheat java, defrost things, and cook frozen veggies.
Unless you use it as a primary instrument to cook I'd go with the cheapest model I could find that fit's the size requirements needed.
They are cheap and getting cheaper so consider them as another throw away appliance of the 21st century.
