If you live in Saskatoon and are looking to pickup an affordable computer that has what you need here are some of the ones I have found in my travels.
The best way to pick any computer is to pick one that will suit what you need. Buying something that has too much for you is a waste of money and you will feel poorer the next day. Buying something cheap is a terrible idea, because with computers you do get what you pay for. So please look into the hardware, and read reviews about them. Then when you do finally get a computer treat it nice, it does a lot for you and trips to techs are costly.
