Regarding Northwest Aviation, I knew one of the instructors who worked there and I have done a few intro flights there. I am from Arlington Heights...so I am pretty familar with 06C ... The IFR there really shouldn't be a problem, typically you fly to Dupage, Lake of the Hills and such if you need IFR plus Aurora etc etc and sometimes you'll head to palwaukee for approaches, its really a good experiences. At least thats what he told me. Also I begain my flight training at Windy City Flyers .. at Palwaukee or Chicago Executive blah blah blah... which is a good place, only problem I had was that i seemed to lose an instructor almost every other week, don't know if thats changed now, but that was my experience with them was good. There was another FBO at Palwaukee that has 2 Archers and an Arrow, I know they moved further North to a bigger hanger .. but I can't for the life of me remember there name or the website, but they offered pretty good prices for training. All there CFI's are independent guys and I know that they had very very nice aircraft, similar to UND's fleet up here. I wish i remember the name... maybe someone else can shed the light on there name cause I know they had a website ... All in all I think you'll get a decent IFR training at any of those schools.... Hope that helps ..
