I have a KwikLift and keep the car up on it all the time. It appears that they went out of business, but there are plenty good used ones out there. Even saw one on this site a while back. It's simple, sturdy and gets your car up about 20", which worked perfect in my low-clearance garage.
You might also look at the Max Jack here. Also designed for low clearance and you have access to everything under the car. They are portable too.
