Is this a good deal for $250? What are its advantages and disadvantages?

I have that fishfinder on my boat and I got it at Bass Pro for about $250 or so.  I really like the unit.  The bottom tracking feature on it, a sonar picture feature, is a option that a lot of others don't have.  I use the bottom tracking screen the most.  It also has other screen types for ice fishing, night fishing, etc...  I also like the quick release, I bought another cradle and put it up front.  So when I am fishing I unhook it from the console and put in up front, put you have to buy the extra cradle.  

Lowrance is also, from everyone I talked to, is one of the top (if not the top) companies in the fish/depth finders.  I really enjoy the x67c, I would say it is the top one without going up to the super fish/dept finders that have GPS or lets you see the bottom like a camera.  

I think it is the best one for the price and what you get.  My best advance is to go to a sporting store that might have one for display that you can play with to see for sure it is the one you want.  I spend about 1-2 hours at Bass Pro playing with each one to find the one for me.

I've got a x67c on the front of my Gambler. It's a nice little unit, no lie. My old x85 got stolen and a buddy let me borrow the x67c until he got another boat. It shows a very clear, crisp picture and I can see a spoon on the graph down about 25-30 ft. When it came the time he needed it back, I went and bought myself one. I think I paid like $210 for it brand new on eBay.
