The embraer 135/145 and bmi regional are the best start you could ask for in aviation... ( unless you can start on a TP of course )
Awesome jet, simple enough to enjoy, complex enough to learn about the systems. Great route network, a lot of fantastic people and good standards.
Proper flying, visual approaches, NPA, as already mentioned no AT, no VNAV and you WILL miss it when you look back one day.
Go for it and be thankful, look around at what's happening, airlines are not going like they were even a few months ago, Norwegian stopping courses, WOW downsizing, I would grab it with both hands.
Best of luck!
p.s.
I personally know of a number of guys who got DEC on 320's directly from bmi on the embraer so nothing is impossible if the market is good.
