100W Poly panel in Home Depot
Don't have a use for solar that small :), but I think the price isn't too bad. You'll have to order, they don't stock it in the aisles. Free shipping, and it is Poly. 100W

Should I stall until a reasonably priced 200W panel is available?I'd say don't stall. The size of the module is dependent on the number of cells. You wouldn't want to schlep around a 200+ W panel. The price of these Grape solar panels is low since there is no shipping involved. I'd suggest to buy two to achieve a 200 W array. A piano hinge or two small butt hinges attached to the frame sides will result in a "suitcase" although it might be easier to deploy them as singles.
As far as roof mounting, there should be no worries about fasteners through the roof membrane. That process has been covered extensively on this Forum. I have not heard of one leak through a panel bracket. For the very squeamish, there is also VHB tape but that is not a good attachment for a membrane roof. It does work brilliantly for fiberglass and aluminum roofs, though.
