the bigger question with panels, is where you are going to mount them...that will drive the size and mounting style...at that point you can shop $/watt...doing it the other way will force you in to an installation that may be substandard, won't work, safety hazard, etc.
Hamilton Ferris is a good place to start.
Blue Sky MPPT controller are well respected and will provide the things you need in a reliable package.
None are cost effective, unless you NEED solar...and plan to keep using them for years. I would suggest that you would need 4-6 years of full time use to break even...as compared to other systems. Nice part is they are very quiet when compared to wind or generator.
They do work, we used two 110 watt panels on our previous 42' and were quite happy, since the new owner did not want them, they currently supply all the power for our 25' RV.
