Yep, just as reliable! I think the only SWFA scope with questionable reliability is the new 2.5-10 (although I don't know if it's even been tested for tracking by anyone yet) and possibly the 1-4? Someone else will have to confirm that one, as I can't remember for sure if there were some early issues that were fixed later on or what.
I have the non-hd fixed 10x and the glass is actually pretty good considering the price point. I don't think you'll be disappointed if you go with one of the fixed versions between 6x and 12x, or the 3-15 if that's what you're looking at. The fixed 16x and 20x get mixed reviews on the glass.
