Good thread, guys! I agree with pretty much all that everyone else has said.
I had the same dilemma a year ago. I had always "fished blind" and done well. The flasher has even made it better.
Fortunately for me, some of my friends own flashers, and I was able try several of them.
I was able to fish a Vex (22?) and a Marcum LX5 right next to each other. I liked both. I have also fished under a Hummingbird, and Showdown Dual and I liked them one as well. I ultimately selected the Marcum LX5, and I really like it. No regrets.
If I had one opinion, it would be to spend a little more to get a higher end unit if you can. You will not be disappointed if it is something you can afford.
If all you want is depth, they all work pretty well, even the "cheap" ones.
