I feel your pain trying to figure out which trainer to start with. I guess it depends on your patience level. I just started flying a few months ago and bought the Hangar 9 alpha RTF. It has been a wonderful experience for me and I was up and flying the day after I got my plane. That said, if you want to take the time to build one, you will end up with a better quality aircraft and perhaps be able to keep your plane longer(not out grow it in skill). Understand that I am NOT a builder, never have and looking at the complexity may never build a kit. There isn't anyone in my club that enjoys building and the thought of spending hundreds of dollars on a scale kit and have to "feel" my way along is NOT appealing.
Anyway, I did a search on these forums for trainers, and I thought the Hangar 9 plane had the least negatives written about it of all the RTF's. But consider, if you are looking to fly NOW, RTF is the way to go. Look into the Hangar 9 Alpha 40 or 60 size, the Nexstar, Hobbico, and if you are looking to get into warbirds, the P51 trainer. If you search you will probably find a lot of information on a lot of trainers both good and bad.
Personally, since I want to get into warbirds eventually I would have loved to try the Hangar 9 P51 trainer, but it just came out [].
Good luck in your search...don't forget to search these forums...it is a great education.
Cheers!
