for the price, from all reports i've seen, you cant go past University Optics for orthos mike. I've not heard a single bad thing about them (except for maybe eyerelief).
I also read somewhere the celestron ultimas are exceptional for planetary work. I think it was louie that had a 5mm for sale?
sorry i cant help more.
like you said tho, you dont need a wide field of view when you have your tracking going
My TV plossl is very contrasty and offers good views but I dont know how it compares to the above. I cant imagine it would be as good.
