There are a ton of good ETFs out there to get involved with. However, if you want a quick return on your money in the current global market, then you will be hard pressed to find a better ETF investment than that of gold and silver ETFs.
While silver ETFs are currently down a bit due to the cutback of silver demand in industries, they are still an excellent buy, as most experts still think that silver will continue to rise over the foreseeable future because investors want to put their money into some stable.
On the other hand, gold ETFs are now sitting at an all-time high, and do not look like they are going to slow down anytime soon, especially if the economy continues to falter. Even when gold does decide to drop, you may have already sold off you ETFs and are now looking at quite a nice gain. You can then always re-buy because gold will always carry a nice price with it.
Exchange Traded Funds can be a tricky beast sometimes. If you are looking to invest in something that will at least hold the value of your money for a while, then gold and silver ETFs are something to look into.
