Opinion on CJ7 lift kits

I need some advice on lift kits.

I saw this ad on e-bay. What do you folks think of this setup? http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=33585&item=2456045624

I just bought a '79 CJ7 with awesome 35" tires on it. I believe the lift on it is a 4" but I'm new to jeeps and things Jeepin' so not really sure.
One thing I am sure of is that it has a little bit of a driver's side sag and the left rear tire does rub when turning right and over a bump like into a gas station or driveway.
I'm not going to be doing heavy off-roading or crawling, etc. I just need it somewhat "beefy" and no tire rubs on the fiberglass body and the intent is for this CJ to be a "daily driver" so a reasonably smooth ride would be ok.
I don't want to spend (another) fortune on this Jeep as I just rebuilt the T-18 tranny and dropped a new 304 in it and would really like drive it now instead of throw money at it.
I know you, Bruce, had that "Shackle reverse" thing going but I don't know how costly or easy that is to install.

Thanks all.

I just noticed in a search that some comments have already been made on the e-bay kit I referenced. I admit those "curves" look a bit odd.
