Which gameboy micro should i buy ??

I came across a store that has a gameboy micro anniversary edition( gold and red). Its brand new. The shopkeeper said it would be hard, but he could get me a full-black version of the micro if i was really interested. Now, I already have a gba sp, but still want a micro before it becomes any more harder to get a new one. I will be using occassionally ,but im buying it mostly for collecting purposes. Which one would be more valuable or wiser to purchase. A jet black version which i would prefer,(but i wont play my micro much,since my sp is for that) or the anniversary edition. I wanted some reccomendations.



Thanks.



Also, is there any thing i should keep in mind before buying my micro? Since its not a clam shell design, what would be the best way to protect the front of the micro? Special scratch gaurd? Special pouch?Which gameboy micro should i buy ??
None, just keep your GBA SP but if you want it get the black one.Which gameboy micro should i buy ??
Go with the anniversary edition. It will be worth more in years to come. ;)
