The Robin DR400/160 is a great aircraft. I come from a background of Archers and Arrows and much prefer the Robin I've been flying for the last 4 years.
Visibility is second to none, I would say actually roomier than a PA28 (maybe just feels less claustraphobic) and being wood fabric constuction gives a great power/weight ratio. I recently went to L2K with 4 adults and bags etc on board with no problem at all.
They also have a slightly higher cruise speed than the standard PA28 (trim out at 115-120kts). They do need to be hangared, but if this is possible I would not hesitate.
