Hey 4cruzin and twofornow, If ya really want to start playing AC/DC on guitar it's easy.
1) Just go buy a good electric guitar.
2)Then spend the cash and get this little monster called a Korg PX4 (pandoras box), it's got a ton of effects, a drum beat, a tuner, different amp sounds, headphone jack(your family will love not hearing you LOL) and you can also hook it up to an amp. I have one and this thing is killer!!!
Here's the link with more info and demos of just some of the things it can do! Make sure you check out the streaming video demo too!!!!

It's called "The Definitive AC/DC Songbook" it's got 85 songs with complete lyrics, ALL of which are in tablature, so you don't have to know how to read music to learn to play it. It's VERY easy to understand this stuff. I've seen this book at Tower Records and Guitar Center.
Sorry didn't mean to jump the post.
