hey,<br><br>am thinking about getting one of these but thought this might be a good group from which to solicit advice.<br><br>basically I'd like to know if one brand generally better than any other, are the more expensive models worth the cost, etc.<br>
<br>also, does anyone know about the "tinfoil hat" factor w/these? are there models that can they be "flushed"/purged by the owner? I remember seeing that the FBI used one against someone in a murder case and while I certainly have no such plans I figure in post-9/11 Soviet USA the less info the govt has access to the better...<br>
