yes the price for the electrity is low now ,and as you said the Ln2 price related to price per KwH
but we have not delivery service for it, have to drive 2 hours to get Ln2 (because of heavy traffic jam not being too far )
Ln2 price not a problem for us but the price of hardwares increased to x3 because the Value of our money have been falling since last year against value of Dollar and euro
