You will receive many responses for trainers but I suggest before you buy anything, that you visit a club and get their recommendations.
You may find an instructor who will work with you, find out your needs and wants, and they can advise you on a good trainer. The club may only have certain types of trainer cords and trainer radios (buddy boxes) that they use and they will direct you towards compatible equipment.

I have heard of a new pilot showing up at a field expecting to be trained only to find out that he bought a radio on the frequency that is used a lot. He had to wait awhile before he could fly. If he had attended a meeting first and met with an instructor, he would have known which frequency (channel) would be the best to order and would have learned that instructors 'own' the field on a certain day and students get priority flight time on that day.

So do yourself a favor and listen to the advice given here but also check into joining a club, especially for your training. It will save you more time and money in the long run.

Good luck!
