I have each type (two different bikes) and recommend both -- the Cateye 7 and 8. They run about $30/$35 at Performance. I don't find the wire to be a problem at all but I think it's personal preference. I bought it for the cadence feature. If you want cadence without wires, you're looking upwards of $100. The wireless one has a cleaner look but sometimes high tension wires interfere with it.
