Truvia (made with Stevia but doesn't taste like it) is great and reminds me of sugar because of the white granules....looks just like it too but a little pricey.
Another great treasure is liquid Splenda (I have to watch my sugar/carb intake closely so when I come across a sugar-free treasure I get happy and want to share with the world

). To me, it's so much better than the packets. The flavor is more intense so you use less, it has less of an aftertaste IMO, and it doesn't have the fillers that the packets have...just pure sucralose. And the little container lasts forever so you save money and can take it with you wherever you go. Also, some have reported headaches with the packets but not with the liquid version so you may want to give it a try.
I get mine from netrition.com (a great site for a variety of low carb and special diet products by the way that are hard to find in stores; also delivery is quick and cheap...$4 ground for your total order and arrives fast). Let me know if you're doing the low carb thing and I can recommend some other products from that site and other low carb sites.
Anyway, they sell the "EZ-Sweetz" brand of liquid sucralose. Find it here:
