if you are in a financial position to be able to just "buy more" on any price drops, then you are not going to get locked out by any price increase imo.
tbh i can't see prices moving much at all in either direction next year. i see a stagnant year ahead so i'll continue to save like mad, cut back expenses and limit risk money in the dodgy stock market. 2013 will be a cash and metals year for me and hopefully i can cash out some of my winning stocks. a payrise would be nice too
