Any recommendations on what is easy enough to use, not overly expensive and will read my wife's 00 ML, and my 00 Infinit. If it matters, I do have a pocket pc (treo 700 W) and mobile laptop with wireless if it is suggested to buy something that plugs into the pda or usb on the laptop. Would be nice if it works on my older BMW's as well. It looks as if there are tons of choices.

Thanks,

Jeff
