What is your budget? Take a look on Craigslist in Atlanta. There are a few listed on there that can be had for $1000 or less but the mileage is a bit more than you stated. Can you rebuild the motor if you have to? Here is a pic of the one I bought yesterday for $1,000. This is my favorite color (Green)so far on a Blazer. It has 167,000 and I'm sure it only needs lower intake gaskets replaced.
