I have one Canon EF 70-200mm f/2.8 L USM Lens for sale.
It is in excellent condition, and has only been used about 10 times.
Located in Melbourne and would prefer pick up, but postage can be arranged.
PM for details.
Not sure if you have one or not, but there are a couple of apps for the iPhone that do things very similar to all of that. Well apart from printing off graphs.
