It all depends on what you're going to do with it. I just wanted mine for current speed/current heartrate and current cadence, wireless and nothing extra I need to buy on the "base" model. Got mine for £50 and the ride distances tally up with the couple of GPS ride tracks I've done. It just hasn't got todays "must have" Garmin logo stencilled on it. I'm quite happy with it and the data it generates and in the end that's all that matters, to me anyway!!
