The ceiling height of your garage will have a big influence on what type of lift you will want. I was able to buy my two post Rotary (used) for $1400 because the person who had it had only a 9 foot ceiling and was unable to get permission to raise the roof on his garage.
How you intend to use the lift will determine whether a two post, four post or scissor lift will be better suited. Two post are better for most maintenance work, four post is better for storing and the scissor lift is better suited to low ceilings.
You might want to consider a used lift to keep the cost down, especially if you want an American or Canadian built lift as opposed to one built in China. Many of the offshore lifts are not certified so may or may not be as safe as those built here.
