Investing in an index fund (US or otherwise) is going to be your best medium risk investment (with middling to good return). There is more QE on the horizon for the euro, though the dollar is strengthening. Minimal fees, relatively minor risk (If you lose half your investment you'll have bigger things to worry about than 2.5k quid), and pretty okay returns. Plus you'll learn a bit about the market so that you can become a better investor in the future.
