If you want something that will do what your 206 does (short, rough unprepared strips) etc, and lift a good load, your best bet is the much maligned Islander. You'll get an honest 140KIAS out of them (not somebodies dream of what they're getting in other gear -I regularly used to thrash the arse of 206/207 with/without belly pads, STOL kits and other assorted bits of fruit over a 40 minute sector), short-field performance has to be experienced to be believed, comes with seats for 10 adults and will literally fly with anything that'll fit inside the door. They're renowned as "an accountants aircraft" in terms of operating costs. They're relatively simple to fly and maintain for a twin -and they say the only thing that's better than a new Islander is a Used Islander!!!
Not sure what purchase prices are running at these days, but you'd get a good honest airframe for a decent price I would think. The only caveat that springs to mind would be the SB170 status... make sure it's up-to-date. The inspections are a bitch, expensive and recurring.
