Do you have any clubs or instructors close? If so, meet with them before you buy anything. They may have a club trainer you can use or they can make recommendations.

There are a plethora of trainers to choose from and you will get a lot of opinions but it's best to find out what your club and/or instructor recommends. I started with the NexStar and loved it. I bought the package and it came with all the electronics, (servos, receiver, transmitter, battery, etc), and engine already installed. It was easy to assemble, and it came with a simulator that runs on the computer. I didn't shop around to see what everything would have cost if I had purchased them separately and as some have mentioned it was probably more expensive than others. Since I was just starting out I didn't know enough about putting it all together anyway, so having it all in one package was ideal for me.

So, look around, join a club, and ask questions before you buy.

Good luck!
