Unless you go to a reseller marketplace you can probably forget Gampel, although I haven't heard it's sold out (yet). If individual games are available in Hartford, they will most probably be in the double letter rows (not good, been there, done that). You may be able to get a good deal on good seats for less than competitive BE games, but for really good games you'll probably have to pay a reseller a premium, or if you're lucky, sit with the pigeons.
Last year there were seats available in Hartford for the upper end zones. Not the worst seats in the world, not the best either.
