Hi Steve,
I will also (hopefully) need to use zigbee if things go my way...
I am thinking of using the Xbee Pro, because of the higher power.

Is it worth buying the development kit, or it's just as easy to buy modules 
and interface to them (MAX232 or so for PC end, straight serial TTL at the 
other end)?

Also, do they really work up to 1 mile in line of sight?  I'd like to use 
them at 1Km, I am concerned about the chip antenna having lobes, and having 
to rotate... or something.

I thought nobody sells 900MHz zigbee, do they?  I'd think I should get 
longer range, and maybe less interference ... am I wrong?

Thanks,

Cat
