LL,

The prices tend to run a bit more, but you might check with several Ely area outfitters that often turn over used canoes from previous seasons.  For instance Piragis turns over their inventorty annually.  Check their website for used canoes.  Usually there is a good selection on manufacturer, size and layups.  If in Ely, they will let you 'test drive' with no commitment and they love to talk canoes.  The cost may be a bit more, but the canoes have only one season on them, you have more options and you'd only have to haul the boat one way....the first time anyway. 

I've never paddled a SR, but have done two person trips in a Wenonah Spirit II @17' with three packs and comfortable amount of room.  A 16' might get a bit tight, depending on how much gear you hall.  I'm pretty light, ie no chairs along, mostly the basics, but not hyper-light, so I generally carry less gear.

Good luck on your search.
