Even cheaper... call the manufacturer directly.
I just bought the 3000# model with the micro-switch stops today. $185 + $12 shipping.
Your shipping may be slightly more, as I am in Michigan, and so is the Mfg.
Make sure what ever one you get, that it has the micro-switch stops.
That way it keeps you from ratcheting the gears when you extend it all the way.
Many manufacturers don't put them in.
