I have a cheap electric focus which is a little better than manual focus but not always strangley..sometimes manual works better fir me...but if you have to come back it suffers from what I guess you would call backlash.
ITS probably good to try one out but it seems the reality is if you are going to get serious you need to set your sights higher.
And be lrepared to pay more for the real deal focuser than you paid for your ota and maybe your mount...
However I get resonable focus but if you want to have it respond to temp change well all I can say is have a look of what you can spend.
