I have several different types and it depends what you intend to do with the canoe.. I run Whitewater and paddle lakes as well as play Ultimate frisbee modified for canoes and kayaks..
for a family boat (I have 3 kids) I generally use one of my aluminum boats, but that is because they are bigger and more stable.. keep in mind that a keel will add stability for calm water but may cause you to get caught in shallow water..
The modern trend is to Royalex or similar multi layer plastic. for cost effectiveness the Old Town is a good recommendation. For serviceable and dirt cheap you might look into the coleman boats..
I have a pelican as well and have had to repair the seats where they connect to the sidewalls, but otherwise they are good boats... Personally I avoid fiberglass at any cost because they break into pieces under great hydro pressure... aluminum and plastic mostly bend.. they can be "repaired" to a serviceable state in the wild with a couple rocks, sticks and a few good kicks... usually...
keep in mind that the aluminum and plastic are often lighter as well...
you can also go with wood ($$$) or with Kevlar or composite ($$$$$) and you can get some amazing boats...
We no nah makes some good mid to high range boats... that is a decent suggestion too..
Shop around.. go to an outdoor store with several varieties and talk to an expert there to get their suggestions too
