Thank you both. We are currently looking at used machines between 1,000-2000 hrs. Unfortunately the T2 would put us out of our price range. We originally looked at EC120s, but quickly found out 4 pax, full fuel, and some bags simply wasn't going to happen. So the B4 already seems like a big upgrade in power, size, and price! But maybe not so much speed? Unless smooth flight is possible at 120 knts?
And yes, we too kinda see 350 NM as stretching the EC130's range, not just in fuel but comfort. We figured a "convenience stop" would be necessary on trips of those lengths. The majority of the time, however, we would be operating between 80-150 NM.
