Oh.. so do you just want an enclosure for your existing Mk1 sled? Yes, in that case, you could just send that to me, and I'll build a box around it.

The current Mk2(a) docks I am making do not use/need a sled to work.

Cheers

(I have a vague tingling that maybe we discussed this once or thrice already, but my memory is rather poor at times..)
