If you were going to replace a generator today; 7.5-8 KW size (these will fit the space avail with sound shield)---opinion on the best choice for reliability, and least hassle to operate/maintain. Like-have to remove 4 things to check and add oil or replace the wp impeller. If someone has particular opinions on the electronic controllers vs. the simple units with regulated RPM and about 4 shutdowns in case of failure for the basic issues, I would appreciate comments. Thanks.
