I've been itching to try mine out. One of the biggest reasons why I decided to get one was because I had previously purchased an UraTama and you can transfer points over to the UraTama from the Deka. The games on the Deka look fun as well. I think it's nice to have a Home Deka, at least for collection purposes. If you're buying from the buyer I'm thinking of, $27 is not a bad price for one (and they're reliable too...everything works perfectly). Jason, a pretty reliable seller on Ebay who sells a lot of rare Japanese Tamagotchis, usually sells them for more. Anyway, there are actually different versions of the Deka out there and binary sums it all up perfectly HERE.
