Car Dollies Needed....Make or Buy??

Old thread but, any further suggestions on good wheel dollies? Thanks!

FIW, I have the HF versions in the picture above your post. I halved the front pair as I felt they didn't need to be so wide. Kind of a PITA having to jack the car up to get 'em under the tires. May be nothing to it, but I feel these rounded ones create less distortion over the winter.
