If you live in LA or the area around, so there is a Greiner ACS900 on sale for only $2,700,- I know very well that it is a great deal of money, but it is only 1/3 of what a new one costs (Cousins 10.300,- USD) and it seems to be entirely new ... I'm considering the even in spite of expensive shipping and customs ... but unfortunately, it must be 115V AC, it is not the voltage that can be found in LA and US in general?
