How to select a program

Hello, I am new to affiliate marketing. I am looking for reselling program. I am thinking reselling webwares.
All programs claim that they are the best, so I am totaly lost :confused:.
In order to don’t make too many mistakes, I need some help.
I understand that I must test some programs to finally learn the one that is for me, but I cannot test all the programs around there. I beleive that I have to make a first selection, then start to test.
Is there any general rules to select a program? How you decide that a program worth a try?
I want to thanks in advance any great guy that accept to spend some time to give me tips to make the best selection I can.
