here is another one...in the west an installer (suggested by UBI)...is selling the boxes for $220 to $250 with 1 year warranty....sounds fair???? there is more, this guy does not want to give you a receipt, so what would happen if there is something wrong with the unit????<br /><br />since there is no proof of purchase then he may not want to fix or exchange the unit....also I heard that someone who bought a unit from him managed to get a receipt from this guy...but the receipt was for a much lesser amount....
