Bottom line. I think you need to spend more than that. For a $1000 you can get a very nice 7" screen but IMHO that is pretty small especially on a 24' boat and its too small of a screen to be useful in split screen mode.
For that kind of money you can get a Garmin 740 (less money), Lowrance HDS-7, or almost a Simrad NSS8. I just put the NSS8 on my skiff and what a difference the 8" screen makes compared to the 7". But if it were me I would look to get a 9 or 10" screen. The new Simrad NSS evo are awesome and the Lowrance HDS series is nice. Good luck but think about spending $2K and you will get a lot more usueable machine than you will for $1K.
