onkyo is hard to find in canada at any resonably priced retailer, i looked in the GTA area anyway...

if you're looking at paradigm, the mini monitors would be great fronts, the atoms are would make great rears, add a cc-190 center and a sub from the above listed links. this would be a pretty killer system that would decimate HTIB

mini's retail for $500cad, look to pay closer to $400
atoms are $280 retail, knock at least $50 off
the cc-190's price escapes my memory at this point in time, but i think it's around $250

that should still leave you about $200 for a sub and $400 for a receiver
