Greg West (cornell's world) sells the herpstats or you can order from Dion directly (spyder robotics) I have never bought a helix so I can't tell you about ordering one. I have not had problems with customs upon entering Canada but you never know. The are both great to deal with and really the cost isn't that much more for a herpstat looking at the total costs of everything else.

Greg is in Alberta so it is a mail order for both.
