Decent quality hydraulic floor jacks are available at Harbor Freight Tools for not much $$$. A friend gave me a 2 3/4 ton floor jack years ago and I've been using it ever since. Like at https://www.harborfreight.com/catalogsearch/result/index/?dir=asc&order=EAScore,f,EAFeatured+Weight,f,Sale+Rank,f&q=floor+jackthank you. most floor jacks ive looked for are triple the cost of a hi jack. hence my interest in one.
I can only suggest you reconsider the continued use of your Hi-Lift. I too thought it was required when I first got into offroading but it wasn't long before I learned it just isn't the right tool for the job. My Hi-Lift has literally not been out of my shed in 16 years now (the last time I used it in 2003 taught me a great lesson) and I've never regretted that decision.
