I bought this handheld from Jim at BOE and like it.

That said, it is my backup and I also have a mounted unit. The unit i bought (also from Jim) is a PS 1000 black box VHF. The actual radio mounts inside your console and is hidden. Then you mount a small plug on the console and the mic attaches to that. All the controls are on the mic, which you can take with you.
I fly fish, and an 8' antenna gets in the way. So I mounted a three foot whip antenna from by digital antenna and the antenna pops off with a bayonet mount. It's very clean and I get good rage with it.
good luck.
