You would need to have the fixed end machining done at both ends and the fixed end machining is were all the money is so it would be more expensive.
I dont do the machining, this is done at a local engineering company so i would need to get a quote.

I suppose you could use BK on both ends, but you'd need to make the ends with a lot of precision (or have a number of different size shims to pad out the end with the screw-thread).
