The Hobbico Superstar 40 looks good to me. As I recall, I went with the Tower Trainer because of their crash guarantee. It's something like if it crashes for any reason while flying with a qualified instructor and following safety procedures, they will replace the plane at no charge to you. At least that's the way it used to be. Of course the grantee lasts for a specific length of time (a few months?)

As far as field equipments, at the very minimum you'll need: Fuel, fuel pump (manual or electric), fuel tubing from the fuel bottle to the pump and from the pump to the engine, a glow plug ignitor, glow plug wrench, extra glow plugs, either a safety stick or electric starter, a way of securely holding the plane while you start the engine, a wrench for removing and installing propellers, screwdriver for removing and installing the spinner. You will also want a field box in which to put all this stuff.
