First of all, I absolutely have no idea who you are. Second, it appears I made that page over a year ago; I was new to here then and don't know why you are discussing it now at this time. Third, that was the picture I found regarding this guy when I did all the voice actors so I naturally assumed that it was him. And fourth, I don't like being berated upon because of a mistake I probably made over a year ago - instead of telling me that, why don't you just post the correct picture of the guy. I'm sure it has probably been updated now and just on a side note for you, it's not a good idea to berate an experienced user and former admin like me. Keep that in mind next time.
Well, before you buy a professional dummy, let me recommend that you practice a bit first because trust me - it's not easy.
As for a dummy, I don't have that many myself due to financial circumstances but I get mine off of Ebay right now because there is somebody whose username is Gepetto something and he handcrafts his own dummies and sells them cheap for people who can't afford the high quality puppets like what professionals use. His puppets are really worth around 6-7 hundred with their features but he usually offers them around the 300 mark with some possibly going higher. There are other places you can get puppets - both wooden and cloth and they can custom make puppets for you but they can get expensive. There is a latex life-size ostrich puppet for sale on Ebay right now selling (if still up) for 5,000 dollars. But really - the way to get started is to use a sock and rubber bands but if you want a dummy - get a cloth dummy first since they are easy to work and when you are ready to take it up to the next step - get a wooden one with features like eyes, eyebrows - you get the idea.
Hope this helps you out.
P.S. I'm actually saving my money to get a custom puppet that can "spit" - squirt water out of its mouth with a special mechanism and that's expensive.
