If you have money for classroom-based training, then go for it because it the best when you can directly speak with an instructor. The problem is that classroom training is usually quite expensive and many people prefer to save money by opting for online SAP training. Also, if you buy online training, it can be taught from any location (non necessary Texas).
You can check the available training providers in US here: SAP Training in USA. If you’re in doubt which one to choose, I think that ExitCertified is a good one.
