Hmmm… seems the askar FMA line fills this quite nicely.

 

Of course, they are triplets. The prices are a bit high for what the PO first posited, but not usually so. Certainly way better than using a CAT 51or the like.  Heck, two high-end Japanese or German eyepieces would more than cover the cost. 

 

Through I don’t know how they would handle the longer optical train with the prism.
