I have had two different 60" Lazers with KawI's and have noticed most dealers seem to be pushing EFI's now. I would be interested in the opinions on why one may choose an EFI over a liquid cooled. Is it just the price differance? I buy new every year but because of my price break as a not-for-profit, I have no problem selling my used mower for the exact cost of a new one considering my not-for-profit discount from factory and average hours at the end of the year on the machine (57 hrs for 2002!). (Exmark Lazer Z 60") I assume most buy EFI because of the cost differance that is harder to pay for when a commercial operation maybe trading every other year.
