OK, thanks for all the help guys. I'm going to go with a Purple Days for the solo events and I'll do some further research into either the Herbalaire or the Volcano. I've read good things on all three of those products, so I'm not too worried about purchasing any of them. Thanks for selling me on the bag system, wasn't too sure before why they were a good thing.

One last question: Where is a reputable source, preferably in Canada, to purchase? US source is fine if they are willing to ship via USPS.

Again, thanks for all the input.
