Wow!! Thanks for the incredibly numerous helpful replies. Chuck, your
Montauk console is very similar to my Dauntless console. My current GPS has
an external antenna mounted to the steel tube running across the top of the
windshield. If I use an internal antenna it would be abour 11 inches lower
than the external and about four inches aft of it.

Based upon my preconcieved notions and the responses here I'll almost
certainly go with the internal antenna.

I'm looking forward to a WAAS unit with a color display and Navionics
charts. Wish a larger display was in the budget.

So far it looks like Tiger GPS has a competitive price at $671 delivered. I
spent more than that for my LMS-160 in 1999.

Thanks again.
