If you're going for a handheld I'd recommend the Lowrance iFinder H2O "c" for color. They are running just over $200 without the mapping package (more for topos, hiking, roads), or close to $300 with the "mapcreate" package. I have this unit and its awesome, very nice color display (go for color it is worth it). The nice thing about this handheld is it can use the Navionics Hotmaps "premium east" SD/MMC card, which has the detailed contour map for Winni. That map is...awesome.
