1st things 1st.
Why do you want one without a button? and are you aware of the advantages of a button over a non-button? (other than the fact that there's a button?) - For Example: Those with buttons can last longer, and are easier to drip with, should you choose to do so. (among other things)
Unfortunatley you probably can't get one from CigNot for $35, because I don't think they ship to Canada. These things are banned in Canada from what I understand.
If you can find a Canadian supplier who sells a kit with 2 batteries, I'd try an auto and a manual, just knowing that if you're in it for the long run, a 510 kit with a manual should last way longer, according to what I've read.
