I'll have to second the idea of the Nexstar. It comes with a simulator, which you can do basic practice on. I would save the engine from the Seniorita for when you get a second plane. You will want to practice on the Nexstar's simulator until you are able to get roughly 20 landings and takeoffs, without crashing. While learning the simulator touch and goes, you will also learn orientation. Also, landing on the simulator is actually slightly more difficult than in real life, at least it was in my case anyway. Make sure you have the "speed brakes" installed on the Nexstar, as they also generate LIFT (I know from experience). Also, be sure to mow that grass strip very closely for less wheel rolling resistance. It's too easy to nose over in grass that's more than 1" thick.

There are some advantages to the Nexstar that other planes don't have. For one, the elevator and stabilizer are easily removed and replaced (they're held in place by strong nylon bolts). The wing bolts down with a single screw. If you damage a fuselage, you can save everything else and essentially just bolt the parts on the new fuse. The landing gear is a bit of a disadvantage, though. You have to make sure it snaps into place completely and give each side a toug. If one comes out, it may have to either be epoxied to the clip through the hole at the bottom, or you might wish to use rubber bands to "bunch them in" where they join the fuse, which ever works. I would opt for the latter.

Considering the altitude of where you live, I can't say how the Nexstar would perform. You might need a long strip, and you may need to fly it fast. So, anything you can do to get as much out of that wing as possible will help. Don't forget to install that simulator that comes with the plane, it's helped me a bunch. I wish you the best of luck, and let us know what you get!
