for $10k you could easily buy a Sami already built and be done. I saw two softtops on Craigslist a couple months back that had about everything a person could do to them already done for about $10k. Not sure if they sold or what but can't find them listed any more.
While $10k seems high for a Sami, the ones that are close to stock and in good condition are selling for $3-$5k here in SoCal. You add lift, lockers, cage, axles, gears, engine swap, ect... and you are getting close to being better off buying one for $10k already built. Key is finding one built and in good shape and not already torn up.
I would add up what mods you think you want to do and then see if you can find one built or if it is cheaper to build it yourself.
Keep in mind that alot of projects tend to go over budget and take longer than expected.
If you are putting CA plates on it, then don't forget about the smog requirements.
oh, almost forgot to mention....
