Recently I was in the market for a GC, for my son's first vehicle. I knew the 4wd and 6 cyl. would be great for him. To be honest I didn't much care which transfer case the vehicle had, as long as it was cared for and had relatively low miles. We found one after about 8 weeks, and ebay was the source. In the search box I filtered the results with closest first, so I could inspect, and drive the vehicle before bidding.
I passed on at least 6 different models ranging from 1995 to 1998, and ended up buying a 1994 Limited with 110k.
I brought my coveralls, floor jack and some tools to check the vehicle out and it was acceptable with just a couple of minor problems.
Best advice is to not be in a hurry, the right one will come along.
