As was already mentioned just get a cheap one to start out. After you practice for awhile what "a good one sounds like" will come to you. I have been practicing for a little over 2 years now. I started at age 61. I have 10 thumbs, but read somewhere that if I keep at it I will improve. This is true! I will never be real good as a guitar player, but progress is very rewarding. Dexterity exercises are important. Pattern recognition is important. Keep at it, when you start to get a feel for playing the guitar you will feel very rewarded, and you will find that you practice more. Good luck and enjoy.
