I was at Menard's, and they have that 3/4" Birch faced cabinet plywood on sale now for 19.99 a 4x8 sheet after a 5.00 rebate. Not a bad price at all!

To address sturdiness, with my straight 3/4" plywood walls, I can assure you they are sturdy-since I have smacked into them several times and I weigh 300lb.  The only place I would use studs is where you were going to position the breaker boxes so you could run the wires inside the wall (with screw panels for access). 

When I first started my conversion I asked one person what was the best interior construction for the cabinets and walls-and he said the method that allows the cabinets and walls not to fall down while driving!  Good Luck, TomC
