If you can go to a regional with 300hrs or whatever, go for it. You may catch a lot of flack on here but you'll basically be skipping a step. Getting valuable time, making at least as much as you could flight instructing (maybe not much more), and if you don't like the company, it wouldn't take long to build the required time for a "better" regional. That being said, you'd really need to work hard to make it through training, and most importantly you do not want to be a burden to the captains on the road.

Good Luck.

BTW, flight instructing was fun, however you have a pretty cool opportunity that not many of us had five years ago.
