I say if you got the money and willing to spend it why not go for it. Do whatever you need to do. Getting MEI is worth in one way, but nonsence in anther way. First of all most school won't give you multi student when you start. They start you as a basic private pilot instructor and instrument. Multi students are fow instructors who have been working for a while. If you go to just about any flight school you will most MEI's stalking their students and basicly ripping people off and do all kinds of stuff just to get each hour in the multi. So I say if you got the money spend it for what you want.
The only reason that I can think of people being so negative about the current low minimums is because people had to work their butt off as a CFI and earh hours for regionals and now kinds with 500 TT are getting in. I'm surprised about peoples attitude about this. Finally pilots are getting an opportunity to get their dream job faster. Pilots should be happy about that. Not ****ed.
