Scopetronix 14mm and/or 18mm

I am looking at purchasing one or both of these strictly for visual use. Any feedback would be wonderful. I have the UO Konig II 16mm, which has the poor edge performance (I emailed UO since it is under warranty, but no reply).

THanks!

I bought the 18mm for visual-only because of the FOV and eye relief. At f/6 it was super-sharp, easy to take in the full FOV and it barlowed (2.5x Powermate) extremely well. No complaints at all. I was surprised at the "premium" performance for the reasonable price. I might get the 14mm also.
