My wife recently picked up a set (front and rear) of the genuine Lexus all weather mats from the local dealer and I think that they ran ~$85 (including 8+% tax).
I had been looking at the WeatherTech, Extreme, and Husky mats and for the set of 4 plus shipping (remember that mats are *heavy*) I was looking at about the same cost.
The mats are very good quality, functional, and compliment the interior well. The only initial thing I didn't like is that the Lexus mats only come in grey and tan (I have a black interior). After installing them, the grey doesn't look at all bad and hides the daily dirt much better than the original black carpet mats did.
