That's a bit expensive. That's exactly what I paid for a 2nd hand DC with 3 original games, 2 pads, a VMU and God-knows-how-many CDRs. Most were badly scratched, but hey.
(BTW, I'm Brazillian too, but I'll keep the communications in English so everyone can read it).
DirectShopping is a pricey store. The only cheap things you'll find there are some mint Saturn games (the last TecToy's batch). Depending on where you live, you might find better prices by looking at some stores (non-online). You might have some luck finding a Saturn tossed somewhere. And those underground videogame stores might also have a few new ones too.
A friend of mine just got a transparent tectoy Saturn (used) for R$150 or so.
