Does anyone have a favorite site welding site for newbies?

You could use BOTH. For light work, like sheet metal, acetylene is
better. For stuff that's thicker, acetylene becomes progressively
slower and more expensive to run. If you compare initial investment,
a used buzz box is way cheaper than torch, regulators, assortment of
tips and cylinders. WAY CHEAPER.

Take a course.
The way I learned (community college) was to take a oxy-acetylene course
first and then go on to learn the basics of arc. The principles are (more or
less) the same, the only difference is the speed of the process.
Understanding the fusion process of welding is key to using both processes.
Brazing is another beast which will be covered in a acetylene course.
Of great concern is the safety practices you will have drilled into you in a
formal course.
To be sure, an acetylene setup is expensive but for my money is essential on
any shop.
Just buying a book and a rig is a good way to get frustrated really quick.

Hope this helps
Ken.
