Another opinion-
If you want to get back into it with what you feel you already know and are comfortable with, go for it! Glad to have you back!
Myself, I think you're eventually (just a matter of time) going to find yourself replacing any/all the "old school" you buy now. Thought being there, don't go crazy building a hoard of what you're likely going to learn is badly outdated. Purchase what you need to go flying, then go do that. While flying, thinking you're going to be exposed to some new ideas. One being things are likely much simpler and more reliable than they used to be (ESPECIALLY regarding gas!), and prices have become very affordable. Yes, there's a learning curve. Just keep an open mind.... -Al
