Hi serratus,
First of all, Welcome to CanReef!
In time with reef keeping you will learn that cheapest isn't always the best. You really, really do get what you pay for with reef equipment.
There is marine aquarium stores in your area, but I'll let someone else chime in on that
But, sometimes the best price you can get on good equipment is to buy used!
