We are in need of a source four with 90 degree lens. Can anyone recommended a good place with cheapest price to buy as we need to install this for a client. Thanks in advance.
Any ETC dealer should be able to get these with ease, although some smaller dealers may need to specially order them if they don't stock them. There are too many options to name in New York, just look at the list of dealers on this site (we do have that, right?) and take your pick. Online, you can't go wrong with names like Production Advantage.
