Snowwave83,
It is rediculous to say all trainers are the same. That is like saying all minivans are the same, or all trucks are the same. All trainers are similiar is much more accurate.
I searched this forum all over and he is right, there are many opinions. But I would ask anyway, or just look those old threads up. Usually when people post why they recommend a plane they give a reason. This will at least give you some idea. He can recognize patterns if many people are saying the same thing about a plane, it is probably true. After you have narrowed your choices down check into the technical specs, product review etc. So don't just go and ask for any trainer. Do a litte research you will be happier.
I am sure you could learn how to fly on any trainer. The thing is, which plane would you like to learn on?
If you decided you want to get a new midsize truck do you just go the dealer and say give me a truck , any truck will do?
There is not a whole lot a difference between a chevy and a ford, but many prefer one over the other for various reasons.
What I am saying is look around and find a plane YOU like. Take every one elses recommedations into consideration and make the choice that best fits you.
And good luck!
