Have you seen the payload restrictions of an Archer? I was flying to Cherbourg the other day, 3 up, only could have 38 gallons of fuel. If you need the speed, the Robin has more (bit of an odd cockpit, but seems OK for those used to it) but if not the only really practical PA-28 is a 161 (or a 201R of course!). The Robin is nicer to fly, even if it doesn't have the handling of the 200. Stick would decide for me though!
