I'm in Phoenix myself and have a 24 miles commute each way, all but a mile of it at 80 in the carpool lane. Luckily, I'm on second shift, noonish to 8ish, and don't have any worries about rush hour traffic. I also love the heat and ride year round. Leather jacket in the winter with goretex gloves, Mesh jacket and whatever my Joe Rocket gloves are made of (breathes really well, almost feels like foam). Perfect for my needs and desires. If the heat gets to you, see what you can find in the way of a cooling vest: fill it with water and keep cool for your ride in, top it off before you head home and you're golden. As for the job being worth it, only you can say. I've done the rush hour thing, and love that we can use the carpool lane, but if the job isn't something I enjoy, I wouldn't do it. YMMV
