Stick with credit unions. Put some in savings, enough in checking to cover bills, and some in cash hidden in your house in case of a bank holiday keeping you away from your money for weeks (read about Cyprus when you get the chance).
Stay out of the stock market... it is due a HUGE downward correction fairly soon. You don't want to get in just in time to lose most of it.
Consider taking some money (in cash) down to your local coin/bullion store and buying some silver and gold each time you get some money. The COMEX, LBMA and the precious metals ETFs have all had huge draw-downs in physical inventories... and those were likely leased. The manipulated "spot" price is bogus and based on paper metals only, with no regard for the physical supply or production. What is coming out of the ground is a lot less these days, with silver on a 9 to 1 ratio with gold... spot pricing is on a 65 to 1 ratio with gold. The reason is that they want to flush people away from hard assets and into the stock market so they can be fleeced. When the COMEX defaults, silver could hit $500 an ounce easily... and gold to $4,000. This is a nice opportunity. Do a little research.
