$150!?
Steph,
Too bad you're not closer to Iowa, I could set you up with a nice 9 or 10TA. In fact, I'm bursting at the seams with Radaranges right now. One thing to watch out for on the Louisville machine is that the control panel has been replaced with Amana's cost-reduced 'universal' style. It looks like glass, but it's not, and the display is no longer LED. Plus it's missing the trim strip below the vent. I wouldn't give over $30 for it.
The sad fact is these just don't ship well (people contact me with horror stories looking for parts from shipping gone wrong). If you ever make a wash-in, look me up, we can get you set up right ; ) -Cory
