Excellent Takahashi TeeGull Mount on heavy duty Slik tripod (as sold by Anacourtes). This has been my alltime favorite mount: alt-azimuth with smooth slo-mo knobs, a hand cranked center column, a 45 deg adapter plate which enables effortless viewing of the zenith (try that on your other famous brand alt-az mounts). Tak also recommends this mount for their 4" scopes. I have mounted binoculars and even an 8 inch f/4 reflector on it with smooth veiwing. $550 plus UPS insured.
