Ahhh, but the benefits!
Peaceful, quiet, lets you do what you want when you want, no neighbors to worry about annoying you...
When I lived in Yuma, which I despise, we had problems with sand/dust getting into EVERYTHING too, so I can empathize. Not only is the stuff horribly abrasive, but I think it has a high metal content, so it can be tough on electrics, I know that! And it seems like it doesn't matter how well you THINK you have it sealed up, the bloody sand/dust gets in anyway...
Well, good luck getting you Inverter replaced. Sorry it costs so much...
