The shutter count is only indicative of how much the camera has been used. The life span of a shutter is normally around 100-150k... but some have gone past the 150k. So... even if it is 25k, there should be a lot of life left in it. Just do an estimated count of shots you would take a month and you will find that it would last you a long time. Having said that, there are also shutters that would die less than 10k.
