There are a lot of different VHF radios on the market. Ranging from $59.00 to as high as $1200.00. Just go the like West Marine, if you have one there, or on line and see what they have to offer. The sales man will point you in the right direction. A hand held will work fine along with your cell phone for lake use. When I run the Inter coastal Waterways, I don't bother bring a VHF radio... My cell phone is quicker and costs me no more than everyday use. I only use VHF if I can't see the shore line in the Gulf on my 26" dive boat, but then I'm about 50 - 100 miles off shore diving...the cell phone is useless there.
