A little more info might assist in recommendations.
- What kind of floor jack do you have that's giving you problems? Depending on the model perhaps a repair to that 'ol' reliable' is the best option.
- What size vehicles do you need it to be able to handle?
- What's your budget? Do you need the cheapest thing that can reliably get the job done for the near future, or are you looking more for a 'cry once and done' jack that should last decades to come.
If we're talking buying a new jack the HF Daytona is probably the best jack in its price range right now (
$20 off till the end of the month), but Hiball dug into one and it's not as impressive as some hoped. I have one. I like it a lot so far. However, if you can spend a bit more a 2ton or 3ton Hein Werner might be a better option for you. You can expect it to perform longer and parts and repair options to be more readily available if/when it does have any problems than you will for any HF or other Chinese-made jack (torin/arcan/powerbuilt/etc) out there these days.
