The Garmin 182C is a great unit. The Raymarine Raychart 435 is maybe even a bit better and has a d=faster redraw rate. and it operates the new Navionics Gold Chart which is better than Blue. The Standsard 150 and 170 use C-Map which is just terrific. The Syandard Horizon 170 does some pretty fancy things with the DSC function on the Standard VHF is hooked up to it. Read about it one their web.
I think the 182C and the Raychart 435 are both $855 at eb4l.com.
All of the above units are very good and you will be happy with any one of them. It is a matter of day to day operation.. (How many buttons do youhave to push to manage specific tasks), daylight view (not a problem with any of these)
Have fun with it.. shop around, go to West and play with them a bit.. see how they feel to you.
Don''t buy based on opiions here ( except the units that are very cumbersome or you can''t see during the day). See which feels right to you.
