PT, Get the bowl gouge. Once you get it practice on some scrap before you dig into good stock. It will not take long to get the feel for it. The scraper will only get you so far. It is more refining the shape of a bowl rather than forming the bowl.
Dano, You do not have to go out and buy the most expensive gouge. As a starter you might look at the ones Penn State Ind. has. It will at least get you started and if something happens to it you are not out that much. Good luck with the pry bar scraper. If it doesn't work look again at Penn State.
I am mostly a self taught turner. It has taken a lot of work to get where I am. I spent a week with my Uncle a little over a year ago and he showed me some things I was doing wrong. You guy's may want to find someone in your area that is willing to show you some "how to". It makes it a lot easier. The few days I spent with my Uncle helped a lot.
