I went through this a year ago when I had a 4 sp and wanted an auto. Apart
from the problem of finding an auto gearbox with most of the parts attached
ie a sizeable chunk of car, every mechanic I asked advised that they could
not do it for less than half a week's work.

In the end I sold the 4sp and bought an auto and I am very very happy with
the swap.

In terms of economics it seems buying and selling is cheaper than buying a
gearbox and employing someone half a week to modify the car.
