Truly a rabbit hole..... the varmints are multiplying!!!!!x3 on the rabbit hole.
It's like buying a lathe or a mill - the initial purchase of the actual machine is cheap compared to all the tooling you're gonna want.
I'd really consider a comprehensive kit for lifting the JL - ultimately it'll save you lots of time and maybe some money. Worst case you'll probably break even on expense - buy once, cry once as they say
That said I'm all for having fun on a budget so if you can only afford $X now and you can't wait, ok. You can always add and upgrade stuff later just know in the long run you're definitely not saving time and probably not saving money.
