A local store has advertised a very cheap 11mm ultrawide eyepiece with a reputed apparent fov of 80 and made by the same Chinese source as the BW Optik 30mm The price is approximately three quarters of the BW-optik 30mm.
I have never tried this 11mm and the only place I could find it on the internet is through a european distributor called ASTROLAN. It has short eye relief 8mm. I imagine that through my f/5 dob the coma and poor correction would render it unusable.
If anyone has used this ep some time, please share your views - I might give it a try if it gives decent results for the money.
