I have the first Pokedex that came out during the debut of the anime. So I can't say it's very advanced or as amazing as your's probably is, but I still think it's pretty cool. :D I have to say though one of the biggest challenges after getting one was spelling all of the Pokemon names right just to look them up. Mind you, I was only about six at the time and so the only Pokemon's name I could spell was Eevee. D: Plus I didn't know you could look them up by their assigned Pokedex number either.
I got that one as well, it was probably my favourite Pokemon accessory I had outside the game (well excluding an awesome Onix that I made myself), it was great to be able to look up all the pokemon and I'm pretty sure I still have it if I look through my parents loft. These days I'll admit I've outgrown the toys but at the time (and for a good bit into my teens) it was brilliant, even though by today's technology it's probably laughable. So if you (or anyone) is still able to get the same thrill I had when I was younger then I envy you, since for me it's just a fond memory of me wandering around the forest behind my house with my Pokedex and Onix :)
