I have one, I have not installed it yet have been waiting for a transducer shield and no one offers one yet. I'm about to just build my own so I can get this installed and start using it. I went with garmin because imo there isn't another comparable unit at the price garmin has for the 93sv. You might check with David at shut up and fish to see what type of deal he can work for you. If you search on BBC there are a bunch of threads from real world people that include pics and video and you can see what the pros and cons are. Wish I could give some first hand knowledge of the unit, I will be able to by next weekend though. Here is a video worth watching of a real world user that scrolls through several features.
