Reneogy 100 watt suitcase panels without controller are available from Renogy on their web site for $225 delivered and $230 from their EBay page.
Even with the extended top there is not room for the controller in my battery box, plus the box is not water resistant much less waterproof. I have the controller in a plastic waterproof ammo type box. There is room for wiring storage and so far cooling does not seem to be a problem (used in mid 90s ambient temps).
