Am most happy with Garmin 182C use paper too but it sure helps finding your way into unfamiliar anchorages. Have paper charts in cockpit to give me the Big picture as acreen is a bit small for that.
got a good price at GPSdiscount.com
Charts are good though not cheap and coverage of areas doesn''t always connect like it ought to. Had Cheasepeake and New York charts but lost map for cape may til Atlantic city. It seems to be pretty waterproof take it in when there is much rain and I am not underway.
