So I got a gift card for Best Buy for Christmas and I'm lookin' online at TV's and stereos when I stumble across fishfinders - didn't know they carried 'em.

This gets me to thinking about how awesome the HD fishfinder screen shots I've seen are. So;

1. Are the lower end HD units good? I'm really excited about the prospect of being able to really SEE what is on the bottom, a tree verse a stump or rockpile.

2. Anyone have any thoughts on the Humminbird - 570 DI Fishfinder?
