For me I guess it depends what you want to put on top of it and if you want new?
I have an old CDR-2 with a 32' 16 element 2 meter beam on it and has been there for years. Made in the 50's and still standing the test of time.
Took it down before the snow hit and going back up when the season here in Canada changes.
I guess what I'm getting at is,, what are you really looking for and for what?
The Hygain CD-45II seems to be a nice rotor.
I hope you will come back and say you are getting a really good price?
Regardless, these things are easy to work on and even my old CDR, parts can still be found.
Happy hunting!! tracker.
