Be confused no more, Rebecca, you got the right one!
If you look on this site, under Sugar Guides, there is a handy guide, which you can print out & keep in your wallet/purse, and yes maltodextrin is on there as ok.
I buy the Brigalow brand of dextrose powder, in Big W, in their home brew section. It's quite cheap. I think about $2 odd for a 1 kilo bag.
If you can't find it, just ask at the returns counter, and they will show you, if they don't have it in stock, ask when, as I wrote them an e-mail and they said they had no plans to stop stocking it in Big W stores.
Good luck with your baking.....
