I just did my own on my '99 venture. Part cost me 13 bucks. If you are handy with tools, it's not that difficult at all. Takes a little time, but it's not that hard to do. hardest time I had was the back bolt on the tstat housing. I have large hands, and you need a 13mm wrench from underneath the exhaust. Tight squeeze and not much turning room. Fortunately, you don't have to remove it completely.
