I have the Standard Horizon 260HX and the newer S-H 471SX, both submersible. The former is twice as big, but has more juice plus an alkaline "back-up" battery pack, so I use it in the cockpit. The latter has DSC, is about the size of a pack of cards, gets VHF, Family Band, Air traffic band, FM, AM and MURS, has a strobe and probably does laundry. That one clips onto my PFD, and is the one I would take into a liferaft.
If you like cheap, basic but well-built, like strictly lake or coastal, Uniden is a good choice.
