i have a torin 10 ton. i rarely use it. just too big and awkward for most jobs.
i have a no name 4 ton that has been beat to hell and back. i wish i had another one.
unless you really need a ten ton i would avoid them. a 4 ton is so much more useful. the light wright and compact size makes them easier to use and put in place. i get agitated every time i have to use that other heavy *****.
