I don't think it matters other than the cost. If you're worried about it go to Skywest. The Brasilia has EFIS but it is so basic there is essentially no difference. In fact, we go between EFIS and non EFIS aircraft on a daily basis. The same may be true for the Saab. Never flown it though.

The biggest place where I figure a little training may come in handy during a speedy initial ground school is programming the box (CDU) or Flight Management Computer (FMC). Boeing, Airbus, Canadair etc. are all different but the philosophy is the same. However, if you're good with computers and can pick up new systems quickly I wouldn't worry about it.

With all that being said. C152. Or a 150 aerobat like I did. A G-meter for private training is a thing of beauty.
