NH quit making 3430's about 2 years ago. Still might be a few "new" ones out there. A 2wd one went for 14500-15000, never priced a 4wd unit. My Father-in-Law had a 1995 2wd 3430. It was a decent tractor, but a little underpowered for farming and definately needed the 4wd. The 30 series was replaced by the TN's.
