I have purchased from Orion before and they have always provided a quality product at a reasonable price. I purchased this because my old rack and pinion focusser on my 12.5-inch Newtonian finally stripped out after about thirty years of use. This focuser is at least as good as ones that cost much more. While it doesn't have a reduced action fine focus adjustment the oversized knobs provide plenty of control. The locking screw does just that the focus tube will not move when it is tightened down. Other Crayford focusers I have used still allow movement when they are locked down. I have seen complaints that it isn't a factory fit for their scope. So what!? Any time I purchase a new item for my scope I expect the need to perform some sort of fabrication or modification to adapt it. The only issue I have, and it's a minor one, is that the eyepiece lock screw doesn't use a brass ferrule. But, there are two of them on the 2" tube so as to reduce or eliminate any play in any eyepiece or camera you wish to attach. Once again, well worth the price.

I purchased this focuser in 2006 to improve an 8 inch F5 optical tube assembly I acquired that same year. I was pleased with the performance of this item. This focuser is put together well and turns consistently in relation to effort applied so that as long as you have a steady hand you'll be fine even at higher magnifications. It doesn't have fine adjustment knobs, which may not be a requirement as long as you're doing visual only astronomy (not taking long exposure pictures) and or not tracking an object with a drive system.
Also, if you're tracking objects manually without a drive system, at higher magnifications you'll likely spend more hands on time tracking your object than focusing, so not much real opportunity for fine focus utilization. Finally at moderate and lower magnifications, focusing is or ought to be much easier, which also lessens a need for a fine focus usage.
