I started using clipless when I bought my Blur in '05. The pedals are Shimano M520's. It was awkward at first. I started with the tension all the way out so it was really easy to get in and out. I learned pretty quick this way. I have since purchased a second pair for my commuter bike. Riding with out clipless pedals doesn't feel natural anymore. They help keep my foot positioned properly and on the pedals. I still fall occasionally, especially when I've stopped quick and didn't think to unclip or if for some reason my brain just isn't focused and I go to stop and don't unclip until I am already tipping. Though these occasions become rarer. I believe the M520's come with cleats already. I'd say try it, give it some time and then decide which you like better. I'm sure there are those here who used to us clipless, went back to platforms and decided that is where they wanted to be. Is it worth $100? With out a doubt. You could probably sell the pedals if you don't like them.
