SOTA Total Eclipse Package

I am thinking of replacing the battery operated string driven motor compliment on my Amazon Referenz TT  with the Total Eclipse Package and I was wondering if anyone has done this as a free standing unit for their TT.  I assume you purchased the housing for the motor as it comes without a housing, but would be interested to hear from anyone who has fabricated a housing.  It appears as though the motor, housing, belt, cables and regulator comes to about $1600.

Am primarily interested to hear if the modification worked out to your expectation given costs etc.
