The plastic ones work great. I've had a set for years that are the so-called "low profile" ones that I needed when my wife was driving a Firebird.
I think I paid about $40 for them almost 10 yrs ago
I'm the same way. My dad gave me a set of metal ramps but I haven't used them in years. I prefer jacks and stands. It's faster too. I can jack the car up in about 2 minutes vs going to get the keys, driving it up, chalking the wheels, and still getting the stands out anyway...I have never owned a set of ramps in the 30 years I have been working on cars and trucks. I use floor jacks and jack stands when I need to raise my vehicle.
However, I have never needed to raise my truck to do oil changes. Which makes things go quickly.
