StNick, it sounds to me like the Volt should be your number 1 choice. It's a two piece design. What that means is that the atomizer and cartridge are one (called a "cartomizer"), and the battery is the other. It's also a very popular unit and well respected for the genre.
Once he's comfortable with vaping, he can move on to the bigger boys on the block which require a bit more knowledge and tinkering. Most people do move on because they are searching for the "perfect vape."
For the Volt in Canada, you can get it here:
Best Vapour, Canada
He will have to fill up his own cartos with juice, but you CAN buy prefilled ones from the States. However, customs have been told by Health Canada not to allow nicotine juice into Canada. Many Canadians do it anyway and it gets through just fine. get him a variety of flavors. You'll be surprised at what he likes best. The tobacco flavours NEVER taste like a cigarette. People tend to have great expectations and end up disappointed. Then they try a mint one, or a fruit one and they love it.
One more thing... most Canadian vendors only allow payment by Interac Money Transfer. This is because nicotine juice is not authorized for sale (Health Canada). Credit Card companies and PayPal will therefore not facilitate payments for these goods. Rest assured that it does NOT mean the company is shady or anything like that.
The owner/rep for Best Vapour is a fairly active member here and is a nice guy. Can't remember his name, but someone might be able to give you his profile link and you can talk to him directly.
If your husband doesn't like his first experience, tell him to come here. There are so many options out there that it would be wrong for him to judge vaping based on one device/juice. Most of us have had to try multiple different devices and juices before finding what works.
