My initial impression of the Sigma Rox 9.0 that I just got last Friday is very good. I've only gotten to use it on a 64-mile ride but it preformed well. The display is easy to read. It's a little bit of a pain to remember to start and stop the log feature, but I think I can train myself to do that. I had to zero out my Cateye Astrale 8 every time I started a ride or it would add my ride information to my last ride and I'd have to figure out the difference to log the ride. The ability to download to the computer and see the information graphically is the main reason I bought the 9.0. It is pretty cool to see how your heart rate increases with increases in grade or when you're pulling the group, how it recovers when you are on long downgrades and how your speed fluctuates, etc. It has auto start/stop capability and lots of features that I think will take a while to understand. You can get one on eBay for around $195 shipped. I think you can also get it at Nashbar (where I got mine) for $180 plus shipping and tax through the weekend. They have it for 10% off list and have another 20% off code at the moment.
