I have a garmin 60c unit that I use to mark structure with, the screen is small but not an issue for me at this time. I think I paid around $200 for it sometime last year. BPS has the Lowrance M68c S/Map FF/GPS on sale for $200 on Black Friday per the flyer I got in the mail yesterday. I'm sure numerous retailers will have various gps units on sale at reduced prices this holiday season. I like my garmin HH, and I've had good experiences with Lowrance procducts, as well. I considered getting a gps/ff but decided against it since I already have the HH unit.
GO BIG ORANGE !
I meant to behave, but there were just way too many other options available at the time.
