For a first time vaper, I disagree about getting a desktop before portable,
unless the desktop is as simple to operate as the Solo. The Solo is incredibly efficient, durable, easy to use, and I must say ideal for many first time vapers (I had not vaped or smoked before using it, and didn't need any help figuring it out).
Since
@troubledblazing is Canadian, I highly recommend using planetvape.ca - especially if you're going to go with the Solo (and possibly accessories in the future). Great retailer and you don't have to deal with potential customs issues (doubly important if you need to deal with returns, you don't want "contaminated" pieces crossing the border). But don't take my word for it, they've got plenty of satisfied customers around here.
