Check the archives for several lengthy conversations about v-nailers, Jack.
I recommend the Fletcher-Terry model 5700. For my money it is a great value. Made in Italy, with more features and less price than the also-Italian ITW/AMP/MiterMite/Putnam/Alfamacchine model VN-42.
Be sure to check United's price for whatever v-nailer you decide on. If you drive to Atlanta for the show next month you might be able to haul home an assembled, adjusted, slightly-used demo unit at a great price.
