The simulators can be of great help and may even get you to a mid-level plane. I learned on a sim myself and bought a trainer (avistar). I also did my solo on the first day without an instructor or buddy box. Now that I have flown the trainer a few times (20 flights), I do think I should have gotten a little more advanced plate than a trainer (maybe 2nd plane as my first). But I do like my avistar, it's a great trainer with ability to do some stuff that basic trainers cannot do. Again, I mostly learned from the simulators.
I'm in the process of getting a 2nd plane already because I feel that I'm ready. Ofcourse your mileage may vary but a good trainer will help you a lot in REAL WORLD flying. Look into getting something like an avistar, alpha 40 or other upper lever trainers.
I'd still try to avoid a low wing plane as I think you really need to get the basics on a high wing first. The sims gives you a good indication on basic flight, orientation, control adjustments and what not. But it cannot emulate mother nature, real flying condition and your flying area. Those will all vary.
Trainers are still a good start, and I've seen a lot of veterans still fly trainers. They're easy, fun and cost is low.
