Hudson Family

I'm really leaning toward the 700 or 750. I checked out the 64s in person at REI. I guess I can't help but compare the screen quality against a smart phone so the 64s doesn't look very good. Also, a little larger screen would be preferable for my older eyes. I can't find the 700 series in person yet. I know the 750 and 750t have the camera which I don't think I need since I would always have my iPhone on me with a better camera. But the 700 has 1.7 gigs of memory versus 4 gigs for the 750. Is this a big issue and worth the extra $100 since they both have SD slots for 32 gigs of additional memory? I was also leaning toward buying the 24K map in SD card form so that would mean only 1.7 gigs of space when the 24K map is loaded. But again I've never used a GPSr so am not sure about how tight the memory can get. Normally more memory is better. If I'm spending $400 should I just spend $500 for the additional memory?

Our family has been geocaching for about a year using the iPhone GC app which has accuracy to +-16 feet if the sky is unobstructed. We've found 55 caches so far and recently placed our first cache container. I've been really looking at a handheld GPSr unit and have been torn between the Garmin 64s and Oregon 750. The live feature, touch interface and larger screen of the 750 looks like a nice upgrade (especially since they seem to have gotten it working according to comments on this thread). I always carry my phone whether in a cell dead zone or not and understand any data transfer needs to happen through a working cell connection in the field. We often use the hint and past logs if we have trouble locating a cache. With 4 kids the price of the 64s looks more attractive but the features of the 750 look really nice and the touch screen interface is more user friendly for the kiddos as they have grown up with Apple devices in the house. I'm not sure if it's overkill to consider the 750 but find myself checking this thread a couple of times per week to see comments on it. Our primary use would be for geocaching, some hiking and biking with Cub Scouts and Boy Scouts. I've never owned a GPSr but just picked up a book to help with the somewhat steep learning curve it seems many have complaints about. Can anyone provide some guidance to help me make a purchase? Should I save the money and go with the 64s or is the 750 a better choice? Any other advice? Our kids are ages 8, 8, 10 and 12 so I'd like to teach them how to use the GPSr once I learn it myself. Our 10 year old is the biggest cacher of the kids. The other appeal of a GPRr is the better accuracy of +-9 or 10 feet to help us get more caches although I know if the person who placed it was not accurate then the GPSr is probably no better than an iPhone when there's cell coverage. I called GPS City and they thought the 750 was overkill and recommended the 64s with 24K map. As a guy who loves gadgets I'm leaning toward the newest, best device but as a dad I should probably go with the less expensive 64s. Thanks for any guidance you can provide.
