Sounds familiar!!!
I took the decision to sell a load of crap i dont use (kit lens, some audio bits etc).
I have also have a couple of friends who have pleaded with me to be the main photographer at their weddings this year. I am doing pre wedding and reception at one, and the entire event at a wedding in poland. I said to both i will need to hire a 'quick' lens at their expense. Hopefully i wont need to hire now (but maybe i should think about a 580 II flash, my yongnuos whilst they have never let me down do worry me!). The hire money can go towards this lens.
I have also been asked by a pro wedding photographer to do some secondary work, so this should give some pocket money.
