Yes the moonlite's are very good , but the other week my old mate Peter had his 150mm f8 SW frak fitted with a lovely moonlite around to do some work on it and do a comparo with my Istar 127mm f8 that's fitted with the LP $99 job.
We both found that there was nothing between the focusers , almost identical in build , load holding ( T2,20mm Nagler , heavy! ) and feel .
Optically , this story is a story for another time .
