PS did a review on VHF units last year. They are very thorough. I believe you can order reprints. They can be found here:
I am looking to replace my VHF unit this year. I have decided on the Standard Horizon QUEST-X GX1500S. This unit is a class D DSC (has two receivers so it can monitor the DCS channel while receiving on another channel), supports a remote mic, and can also function as a repeater for speed, course, and location.
The price is reasonable - about $150 from a lot of on line places.
