There is some talk in some circles about moving to Euros, and some contracts pay in currency other than the US dollar. Personally, yea the dollar is down and everybody is crying the blues at the moment, but the US economy has been very resilient in the past and I expect it will be the same in the future. So, I'd be a bit careful about going to Euros, when, frankly, the EU economy as a whole is not much better than the US, the bureaocracies in the EEC are killing many areas of trade such as agriculture, where in the US ag trade is up 20% year over, and will likely continue to do so. Your manufacturing is also well up, as are inbound tourists (I think 10% year over) so I wonder if the downturn will be, relatively, short lived. Also, many places with a strong dollar (like New Zealand) are that way mostly due to huge interest rates, which is not a great idea either.

Long and the short from a grass is always greener perspective, I'd just suck up the low dollar as a change will come sooner or later and your employer won't be so happy to change back.

And from what I have seen, yes, contracts are getting better; not only monetarily, but also with commutes.
