Having trouble finding a GBA game case (in Off-topic)

My son has a GBA. Games are super cheap now so I got him a dozen or so. I'd like to get some kind of organizer case for the games, but I haven't been able to google a good one. Ideally I'd like just a case with a few dozen slots for games, but if I have to buy a case with space for the GBA too I'm okay with that.

But I haven't been able to google one except for this one on amazon with a one star review that doesn't inspire confidence. ("Buy anything but this!")

Suggestions? (Please link where to buy, it doesn't do me much good if you like the XXY case that nobody carries anymore.)

Here is one I found on ebay.
Carrying Case on Ebay

that can only hold 4 though

i have something like that... idk if it can hold over 6... but this one can hold 9 and a DS (bigger than a sp so should work No problem) http://www.jr.com/JRProductPage.process?Product_Id=4094182&JRSource=googlebase.datafeed.SCX+DS-S7341

Here is just a game case. It does not give information as to how many games it can hold.

or you could always just get him a 6 game carrying case, that holds his game boy too... (doubt he will ever need more than 6 games at a time) and maybe some protectors for the rest or something :D
... if that fails just get him a large suitcase,... he will have room to put many a gameboy game in there... and... maybe some clothes... a pillow, blanket... a fridge... you get the idea ;)
