If you are only considering getting the CFI as a resume builder, or instructing "just to build time", skip it. The pilots that enter the CFI world with the thought that it's just to build time do a disservice to their students and the aviation world as a whole.
Regionals don't hire pilots with 200TT as you claim...they can't due to the regs. Maybe a place like Scenic can do it, but not the "regionals". They require an ATP.
If somebody will hire you with 200TT, you better latch onto that because it's rare.
