Believe me, I'm jealous. I'd love that extra real estate. But, even though it's going to be an all-in-one unit, it won't be any cheaper (of course). I'm all in HDS-7 Gen 2, LSS-1 w/ducer, & Airmar P79 for <$1,100. Who knows exactly what the HDS-7 Touch will go for when you're all-in (BOE Marine - Marine Electronics and Outfitting - Lowrance, Garmin, Simrad, Raymarine, more!
). I'm thinking at least $1,400-$1,500 w/ transducer(s)
I've just got to be happy with what I have...same thing goes for cell phone, tv's, etc. If you buy new, you just have to know it will be outdated in < 1 year! (though I did just get a new cell phone but it's a 10 month old model and my tv is a 27 inch standard crt that I bought for $199 in 2003!)
