TakeItEasy, you don't have to go high dollar for a jack. If you have a Harbor Freight in your area, you can pick one up for around 40 bucks with one of their coupons. Get a regular height one, not one of the "short/stubby" jacks.
You can also get one from Amazon, Tractor Supply, ect for about 10 bucks more.
I wouldn't have recommended a 20 ton unless necessary. I tried an 8 ton and 12 ton that I had on hand, and both were a bit_h to use. The added power and leverage of a 20 ton makes jacking easy.
