On the subject of cost of power and stupid big lights and bills:
Thanks to the economy, I now qualify as low income with my electric company. There is a fixed rate I can get on being under 35k I think it was, still working on it, but anyway you can get a flat reduced rate bill no matter how many thousands of watts you run it will be at the base rate per kw/h rather than going up the more you use like normal rates.
It may be something others could take advantage of... Check with your power company.
I am legal/medical. No worries about power consumption.
