It depends on the titles or the titles that are offered with the SP. I already have a copy of Iridion 3D that I think I got for like $2.50 at my local mom and pop store. I am looking for about a value of $75.00 in used GBA stuff for the copy of RE2, because that is the current value I can get on Ebay but that would also be around the value of a small used GBA SP bundle on Ebay also.
