Looking at Trailblazers -- would like an opinion

I'm looking at two Trailblazers, neither of which is exactly what I want.

The first is a 2002 LTZ with lots of nice amenities and 50,000 miles. The quoted price seems reasonable at around $15,000. Still, that's a couple of years and about 25,000 miles older than I wanted.

The second is a 2005 LS EXT. That's the BIG Trailblazer. It only has

14,000 miles on it. Again, the quoted price is not unreasonable at $24,000. It's still under warranty, but it has the V-6 rather than the inline-6 and, well, it's big. I'm concerned about maintenance and fuel economy -- I don't really need a truck that big.

I am currently driving a '96 Blazer with 140,000 miles on it. My kids are bigger and I could really use a slightly larger vehicle. Also, the Blazer is coming up on 10 years old and parts are going to start getting expensive.

I'm inclined to hold out for the LT that I want rather than one of these two, but that could take years and I refuse to pay $30,000 for a brand new ride.

Any Trailblazer owners out there have any opinions about this situation?

Thanks.
