This is talk. Threads for gaming systems go into the gaming forum. This forum is meant for discussion about things in everyday life, aside from games. So yeah, I'm moving this.
Also, you're not in charge of who can or can't post in threads. The staff is.
On the topic of Gameboys, I think they were a system made in a time where no developer really had any idea what to do with it, nor really understood its limitations that well. This resulted in it getting decent games, but none of them are truly fantastic. The Gameboy Advance is another story, however.
I always had a Gameboy Color, so the Game Boy always seemed more like an ancient relic. That said, it was the start of great series like Kirby's Dream Land and Wario Land (aka SML3). Not to mention it started the whole Pokemon craze and pretty much made Nintendo the dominant force in the handheld market.
Technically you could still order it online through eBay or Amazon. In fact, here's one up in auction right now, and you could probably find it for cheaper in the Japanese eBay site. (or on sites like Play-Asia that sell a lot of Japanese consoles) Plus all Nintendo handhelds up to the 3DS are region-free (except maybe virtual boy) so you can play all the Game Boy games you already have.
Nope, that's free too.
Rule of thumb when collecting is that handhelds and things with their own screen are region free, due to there not being a certain signal frequency required to display picture on a cathode ray tube.
