Good jack kit to get?

I’ve used an inexpensive 2 ton floor jack (I think I bought it at Sears) for years and years and never had any problem lifting even my truck. In retrospect though I wished I had focused less on the “tons” and more on the minimum and maximum lift dimensions. Especially the highest dimension it will lift to. I often have to add spacers to get my jack to lift high enough that I can fit the jack stand underneath. The jacks with the higher lift specs are often rated 3 ton or 4 ton, but even if you don’t want to lift that much weight, I think it is still worth it to get a jack like that if that rating provides the lift dimensions you need. Makes the job easier.
