Source for purchase of garmin gps

Am looking to purchase a Garmin Map 76. I have a Map 76. Need to replace.
Is the difference in price between the Map 76,76cx & 76csx worth the difference? I am leaning toward the high end 76csx.

I did not like the map76 being slow when barely moving.

Thanks for you input.

Forgot to ask if anyone has a source with a good price, say better than Bass pro?
