well, it comes down to who your market is. I think that while there is a lot of escrap to be had, it will dry up relatively soon given the state of the economy and a lot of people looking to make a buck. i'm not sure if it is possible to "go big" without a ton of capital investment, though. It is sort of like the new home construction business. So many regulations that make it difficult for mom and pop builders to survive. Skilled people end up going to work for a corporation, thus weeding out the small guys fast. If you are just looking to make a few bucks here and there part time, its not so bad. But like olddude i think that in 5 years this biz is going to be drastically different than today. My guess is that if i'm still in it i'll be working for someone else.
