Inexpensive alt-az head?

Biggest problem though is
it tends to get stiff if its very cold. Wondering if there is a better
grease
to put in there and how do you get the bogen head apart?

I would try some silicone lubricant, available at many dive shops. It's very
smooth, resists extremes of weather, and I've used it myself on the focuser
of one of my refractors, after I removed the nasty glue-like "grease" that
was originally used. Works like a charm.
