investing in the U.S. Dollar. I need your help please!

what instruments are available to longs.  personally i want a long etf or mutual fund.  right now all i want to do is track the nav's.  it has fallen so much i think there is a lot of long term value and getting in on an upturn seems to me to be the right thing to do.  again I am looking for the symbols of stocks, etfs or funds. 

so far i have found this fund RDPSX.  any more?

Don't fight the rip tide.  It might be good for a day trading if the FED doesn't cut.  That's it.  The FED needs to protect housing prices to keep the banking system from imploding.  The only way to do that is to incease inflation to write off the bad loans.  The FED has only started to open the flood gates.  Europe will follow with rates cuts and Asia needs to step up and appreciate thier currencies. Start buying goods rather than collecting currencies.
