Recommending that to a beginner is a terrible idea. If someone really has the determination to learn, they need to learn properly. It's one thing if money is an issue, but to intentionally neglect the use of a teacher is foolish :)

Since you have a background in classical piano, are you looking into classical guitar? A qualified teacher should have a music degree. If you're not looking at classical guitar, it would still be best to find a teacher with a degree, and not someone who is simply self taught, showing how they learned something. A good teacher will show you good technique and teach you how to learn songs. A poor teacher will only show you songs. You might find this one to be more enjoyable at first, but if you're only learning songs, then you'll be missing out on many basic technical and musical fundamentals of the guitar. You can always check with your local college/university to see if they have graduates who are teaching in your area. Best of luck!
