I am a fan of starting inexpensive to learn and test the waters. Buy a used complete package with low or medium aspect wings. Then if you like it and want to advance, you can sell the used package for pretty much what you paid for it to the next learner, and then upgrade to as fancy a long term model as you like and can afford.
The learning curve seems to vary from a horrendous process of dozens of miserable sessions, to those who get the basics in a half hour and have base competency in their 2nd session. With this much variation, it is difficult to get good advice on here, as it depends on where in this spectrum both you and the adviser fall. I think I was in the middle somewhere, learned behind my boat, hated first couple sessions, then started getting it (especially once learned to start SLOW Something I observed: a friend recently got the slingshot 3 mast flight school option (used, relatively cheap), and he was up and riding on the first session without any trouble, on 15" mast. Graduated to 24" mast after maybe 3 sessions. Then maybe another 5-6 graduated to full 35" mast. He didn't have the misery I have seen others go through, so it may be something to consider.
