An airsoft pp-19 exists but I've never seen one for sale or heard any first hand accounts of its quality. TM makes a good MP7. The only good MAC-11's I'm aware of are all gas which would be out of your budget. Please be aware I do not advise the MP7 or MAC-11 as a primary weapon. From what I've seen of the PP-19 it might do as a primary, but locating one in Canada is going to be very difficult.
