Though I will be upgrading to something more advanced, I am using the EZ Commander for now, and having a BLAST with it (yes, it's limited, and yes, it is kinda like that first car) but I too would LOVE to find the walk around companion... and I'm still a bit disappointed that Bachmann canceled the wi-fi interface for the EZ Commander... that could have been SWEET! (and who knows... had that actually been made, I might not feel bothered to upgrade... I am only planning a small layout, after all)
