18-inch wheels -- economical suggestions?

[geno]

If I didn't want to mortgage my house....

What, in your opinion, should I look at for 18-inch wheels?

I currently have 17-inch (stock) on my 1999 Boxster. I was thinking I could dress it up a bit with some 18-inchers -- however, I don't have the deepest pockets.

I would prefer not to go over $1000 for the wheels (please don't laugh)

I can get the tires from a friend at no cost.

Thank you as always for your time.

BTW, I put the 2003 Boxster S exhaust (muffler) on my 1999 Boxster. It really did make a nice improvement in the sound below 3K RPM.
