Thinking about new wheels for the DD...

Found some 20" wheels for my Grand Cherokee on Craigslist for $600 with good tires. Want some opinions if I should get them, or not?

Here's what my Jeep looks like now (not my actual jeep, just snagged the pic off Autotrader, since it's identical):


And here's the picture from American Racing's website of their RT-S wheels, and how they'd look on my Jeep:


Think I should grab them? I'm also going to tint the front side windows to match the rears.

I emailed the guy to see if they're still available, but haven't heard anything yet. The only problem with getting these is having my tire pressure sensors swapped over from my stock wheels, or spending $120 on 4 extras to put into these wheels, since it has the tire pressure monitoring system. This is practically a steal for the wheels though. I would imagine the tires alone would be close to $500 new.
