As far as meringue powder, I'd love to try the McCall's MP that Antonia74 uses. I haven't been able to track down an internet source to order from. So far I've only seen a link for the McCall's store in Toronto, but there is no ordering option. I sent them an e-mail today and will let you know what the response is.
The different natural flavorings sound interesting. I think I'll order a few things from the link Tracy provided (Thanks, Tracy ) and try them out. Sometimes I hesitate to try new things because I don't want to flop a recipe with the time and ingredients invested but I realize that it's the only way to improve or change things up. Thank you all for sharing your ideas
