I've got a couple of different coil spring compressors like this one, and this one. I had one for decades and another I got at an estate sale down the street. I hate them. They flex and bind and then tend to gall the threads. I was thinking about buying something more robust, but I have no direct experience with other types. If any of y'all have used something else you like that's not like thousands of dollars, I'd appreciate input. I was looking at things like this hydraulic one or maybe this hand crank one. But then again those take up a lot of space and could never be used for some "on-car" applications so I was wondering if one like this one or perhaps the clam shell type would work better than the ones I got and be useful over a wide range of potential applications?
