Good job! It's great to have opportunities to change positions within a company. I must be perfectly honest with you, the prospect of work at the DRC really scares me. But let's take a look at the pro's and con's.
1.- Interesting work.
2.- Different area, which gives you an opportunity to travel.
3.- Better pay, more vacation time.
4.- Different project.
1.- No infrastructure whatsoever. No access to phone or internet.
2.- The very real possibility of getting killed.
3.- Not staying with the same office for a long period of time.
4.- No possibility of moving around alone.
The big one, I think, is CON number 2.
