Whenever my none smoking fund hits the amount I want to spend on the piece of kit I really really want (there is a plan) ;-)
Gave up smoking last year when I realised how expensive this lark could get. Admittedly my spreadsheet has a fair number of IOU's from the last 12 months but am on a roll now. $9200 so far since quitting and totting it up every week. More importantly, there is food on the table and I havnt hocked the wifes camera kit to get the next scope

..oh yes, and am healthy and dont keep loosing my night vision whenever I spark up!
Upgrade..naah, get it right first time! ooh, then change your mind...
