If you can buy online do so! You can buy the Paasche VL at Dixie art for $45 US. Even if the exchange rate was 25% (which it isn't) and the shipping was $50 (which it shouldn't be!), that's only $106 CDN. There shouldn't be duty as it's made in the US, and we're supposed to duty free. Another lie our governments told us!
My recommendation (as a newbie to airbrushes and proud owner of one) is the Badger 150 Medium but here's a real deal from Bear Air for only $66.50 US:
http://www.bearair.com/prodinfo.asp?number=100009This gives you all three needles and head assemblies (fine, medium and heavy, the heavy being pretty well excess for modeling!), a braided hose, a color cup, two bottles (one with the fast blast tip) so you're pretty well good to go. Attach a decent compressor and you're off!
