Woot has a Bushnell ONIX 350 Color Handheld GPS for sale for only $60. I don't know anything about this model, so I can't vouch for whether it is any good or not, but the price is right if you need a backup GPS or are just starting out.
If you aren't familiar with WOOT, they sell one item a day. This will be for sale today only or until they run out, whichever is sooner. I have bought things from them in the past, so I can vouch for the web site.
