Or if you want one to keep and reuse many times I recommend this one. http://www.amazon.com/dp/B0072W3LWS/?tag=cakecentral-20+stand . I have one and it's very sturdy. I can also hot glue ribbon around the edges and it doesn't damage the surface. Although, when I bought it I don't remember it saying anything about being on "Shark Tank!"
If you go on Etsy and search for "cupcake tower" or "wedding cupcake stand" a whole bunch of them will come up. There are some reasonably priced and some that are really expensive. I like the ones that come unfinished because they are a lot cheaper and you can paint them whatever color you want :)
I have the same cupcake tower as @4Laynes, only I have the square version (link: http://www.amazon.com/The-Smart-Baker-Square-Cupcake/dp/B0072VZ5HS/ref=pd_sim_hg_1?ie=UTF8&refRID=1PBSTN203SJ7SB7G58R6), and I also use my glue gun to change out the ribbon depending on the event colors. It packs down flat, cleans really easily, mine came with a carrying case, and is very easy to put together (I keep a small mallet with it to lightly pound the pieces together). I also like that I can set it up to use all 5 tiers, or just a couple, depending on how many cupcakes for that order.
