Ok if some people are having trouble here:
Its a arduino nano R3
I DO have a pencil Soldering iron with some soldering skills(if i cannot solder part i know someone who can) i have had some training on small parts(old circuit boards from damaged devices (xbox 360's mostly))
The Quartz crystal is a 16mhz SMD Quartz crystal (Cant find on sparkfun Or at maplin)
Im from the U.K
Hope some of this info helped
Try Farnell (whose web site seems to be down at the moment) or RS Components, both sell SMD crystals.
PS - rapidonline.com has a few as well.
