well i got a legend Hcx as a up-grade from a foreterx 101 and i love it. as far as i can tell the high sensity receiver was well worth it for me. I was able to get locks where my dad couldn't (he had a meridian color, which he later upgreded to a vista Hcx). 1 gb shuold be able to fit the whole US. I wouldn't know if its the same USB port, but if you buy new a USB cable should be included.
