Oil Change Automation

Over the years, I've tried various approaches to simplify changing the oil on the diesel engines on my boats (all of the previous approaches were ad hoc, messy, and required retrieving and stowing messy oil changing gear) - this year, I want to try out something a bit more automated.

ReversoPumps.com has a pump in particular, the OP-6, that looks quite interesting. Their web site lists a price of $265 today for the 12V models.
