I hear you mate , they might have a smallish FOV (
but so do Orthoscopics ) but yes , as you say well made ones do perform surprisingly well , also this scope with a couple of those sweet GSO 'super views' will fix any short falls the Kelners bring for very little money , but really they are plenty good enough for any beginner .

You rarely see Kellners today except as "intro" eyepieces with entry level scopes- although good quality ones can give great, narrow field views, and if they have good coatings the light through-put can be very good due to having only 3 glass elements...
