The answer to your question is, it depends on the model of smoker you purchase. Some smokers will have the option to be setup as a grill, others may not. I'm a computer programmer from Burlington, ON, so I have no interest in BBQ retail. That being said, I would recommended checking out a store like BBQ's galore in Burlington. They have a wide selection of "toys," so you should be able to find what you need within your budget. The Burlington one is on Harvester just East of Guelph Line. There's one in Oakville too, but I'm not sure exactly where it is. Google them and you'll find the website.
Based on what you usually cook, I would recommend not getting an offset smoker. Good offset smokers are expensive. Unless you're going to smoke on it weekly, for the money you're investing, you'll probably be happier with a simple charcoal grill like a Weber performer. As a grill it's great, as a smoker it's ok. Temperature control can be frustrating at times, but if you're only smoking a few times a year, you shouldn't have any issues.
It's your money, so take the advise with a grain of salt.
Hope this helps.
