i would it expected to move back towards 1.50 level, i would use a FX broker to put a limit order into the market (best case sinareo - instantly buys at desired rate)
and i agree with ccraig i would allways recommend getting a comparison with your bank and a fx broker like currency.ie or omnisfx. And use the one which offers you the best rate.
it would be a better time now if you havnt allready. had a look at a few graphs of the EUR/ USD market and seems like the Euro will continue to weaken against the Dollar to around the 1.31 level.
