Phil,
Tacktick has a lower price point wind pkg that includes a 12v powered display rather than a solar powered display- price is around $625 +- vs. $1100 =- Masthead unit is still wireless which is the big + in my eyes.

Depth system is around $790 +- depending on where you buy it, you can do it all for about $1450.

I would check the boat shows too, these guys are looking for new customers.

Most people that I've dealt with like there Tacktick stuff.
