"....... wondering if the Rubicon was realy worth the extra $$$."
No, but it's a fantastic rig right out of the box. You can keep the pricing reasonable by ordering without all the accessories, A/C, etc. plus, if you look around you may be able to find a dealer willing to do a feww hundred over invoice. Apparently DC has some incentive money on them now.
As the man says, "it depends." IMHO, the best all around SWB Jeep that's available in any numbers is the 97-present TJ. Next is the 91-95 YJ Wrangler, which are out there in significant numbers and can be picked up very reasonably.
My heart-stoppin' favorite is nearly any year CJ, but they are prone to severe rust damage in wet/Northern climates and are becoming more & more difficult to find in good condition. Clean, rust-free stock CJs are beginning to command premium prices from outfits like Collins Bros. Jeep and Austin Jeeps, etc.
