Minn Kota on board battery charger

[Joe]

I am looking for an on board battery charger that is good, yet inexpensive, mostly for day/weekend getaways. I am considering the Minn Kota OBC-20. Does anyone have any input for me on this model or suggestions on another model. Thanks.

If this is the model Cabella's sells for $120. Both my son and son-in law have this model and they seem to be happy with preformance of this unit. I have a Guest which works great, but costs twice as much.
