I have a 75W that came with the van. It's worth having, but I'm not sure I'd pay for a new one.
The problem with solar is that it produces most power when you least need it - great in the middle of summer, but pretty useless parked in a valley in January.
I think the best electrical bang-per-buck you will get is one of the alternator charge controllers as sold by Sterling Power for about £100. These make much more effective use of the vehicle's alternator to charge the battery. Having said that it's about the only bit of 12v charging kit I've never owned and the grass is always greener...
