I'm not in a position to buy one yet, but I too would be interested in comments/reviews for when I get the opportunity to set one up.
It all looks good to me. The only concern I have is the opening is 200mm short of zenith. I'm just not sure if this means the scope/pier should be offset, or if the offset of an EQ mount pointing at zenith is enough to clear it
. I suspect not quite...
I'm interested to see what others think when they start using them.
