Just my two sense but I have worked on and installed just about every LU/LA elevator available in the US and by far the easiest to install and best running is the one manufactured by Custom Elevator out of Pennsylvania. They use Columbia doors and a GAL operator. Now if you have really good mechanics and some patience and want to save about 8 or 9 grand then look into Elevator Concepts out of Detroit they have been recently acquired by Wurtec and may be operating under Wurtec now. They also use the same doors and operator both use a Blain ev100 valve as well. Personally I would spend the extra money for Customs package it really is top notch.
