Garmin 450t vs 62st

Looking to purchase a gps, garmin 45t or the garmin 62st and not knowing a lot about them, was just curious if any hirers had any experience and preference on one or the other. It will be used purely for hunting.

Went to Cabelas over the weekend and looked at the 450T and the 550T since Cabela's had a super sale on them (I think it's still good for a couple of weeks). Was told the 450T is being discontinued so I opted for the 550T and bought the GPS State hunting map for NM. Will be trying out this weekend but not in NM until next week, I'll let you know if it was worth the couple of hundred bucks it cost.
