Enamel vs Acrylic & Spray Booth

I'm used to spraying the exterior of my 1:24th scale cars with (mostly) Testors enamel spray cans or sometimes factory touch-up cans, such as i.e.- Duplicolor. I've always sprayed outside during warm weather or in the basement. But we moved and no longer have a basement and it's too cold outside during the winter. Now I'm moving up to an AB for a better quality finish.

I spray both opaque and semi-transparent colors (enamel) with a high gloss finish.
Would I have similar options and results using acrylics?

Spraying enamels indoors will require an additional $80.00 (approximate) investment in an exhaust fan/blower for my spray booth to deal with the volatile fumes.
Would such a blower moving such high CFM's be needed for acrylics since it's mostly over-spray that's a concern?

Or should I just go ahead and build my spray booth with the blower since I spent a lot of money on everything else, why skimp now on the booth? That way I can spray anything.
