Yeah it's really sad that with just a little more engineering and execution these mass produced mounts could be at least 50% better. And it would only cost another $10. And it's double sad because some of these have been produced for years, yet they keep on producing junk; well, sometimes they turn out ok. But they're so inconsistent. In any case I still think the market is wide open for someone to produce really good mounts that aren't much more than the mass produced ones, and yet considerably less than the premium brands.
Some good, but inexpensive alt/az choices, such as Universal Astronomics (UA), are no longer on the market except for the occasional used scope that pops up on the CN classifieds, so less incentive for the surviving manufacturers to improve their products.
I chose a DM4 for my 92mm scope. It works very well, but it’s very expensive. Would probably have chosen another UA mount if Larry was still operating UA.
