Going by the picture it's a Skeleton Saturn without the "This is Cool" logo. But there's no guarantee the actual for-sale units look like that (though Tec-Toy did produce many rather cool variations of the SMS).
They must be contracted by Sega to only produce them in Brazil, which now means you have to find someone or somewhere from Brazil that is willing to sell one, sounds like i might have to take a look around.
A friend 'o mine just got a Tectoy Skeleton Saturn. It's pretty much the Japanese unit, with the region modified to US and the color system modified to PAL-M (basically, NTSC with PAL colors). The logo is the Japanese one, and also is the BIOS.
Ah, it's prolly a model2 too. Tectoy's models always reflected the Saturn models being sold in US (mine is identical to the US model1 Saturn), then when the US produciton halted, they started selling the Japanese models. There are both white and skeleton Tectoy Saturns (but only skeleton ones are made nowadays, I think).
Actually, they are (or at least they used to be) something like "Sega Brasil", they are (or used to be) officially linked to Sega, like Gradiente used to be with Nintendo. And although Tec Toy apparently still produces Saturn and Dreamcast, I can only find SMS and Mega Drive for sale.
BTW, recently I've been to some kind of flea market and I was impressed to see how active the market for old games is here.
