I have looked at them
I was considering on buying one for indoors,the lenses are the finest....I like the true diopter magnifications.
I guess if money is not really a issue buy it.The lenses for them run as much as how much the housing alone is practically,I can buy a whole classic setup for 35 dollars more housing lense and all,it also depends what size you get as well.pricey lenses.
I shoot a classic with a.010 downpin,just set it up this way,I am starting to get aquainted with it and the relationship is working.
The housing on the sureloc is wide open so that light can get at the fiber,I think a inclosed housing with a light setup(LP)is nice just because of the glare you can pick up outdoors on a sunny day,and if you are caught in the darkness the light is awesome.You can see the classics due to the 10 inch fiber that runs around the whole outside of the housing.
If your just shooting indoors in my opinion it probably is the best made.It really is a matter of personal preference,who knows maybe I will break down and just by one myself.One very nice scope for sure...
