A second here for torque pro. Paid for its self on it's first use.
I've just ordered one of these http://www.amazon.co.uk/Aoyue-474A-D.../dp/B00FDOP2DI
For that money you could have a chicken coup, a handful of layers and food and bedding for a year. Eggcellent!
Or how about ...
Make some time for yourself.
Not know that Christmas is less than a month away now? get it spent on friends and family :D
How about 'buying' education for a child in a developing county. Mine costs £40 a month, I met her last month.
How about.....save it?
Seriously. Save as much as you can while you have money, because you won't always, and the day you want your own home you'll be sitting around wondering where to get £10-30k from.
Shares in Ubiquiti!
Save it, unless you plan to live at home forever. Set up a standing order into another account each month. This year I have over £3k thanks to this method. I have a mortgage, car etc.
If you want to spend it, get a go pro to go with the quadcopter. Then you will need a new laptop too!
