Are both of those models capable of playing PS2 discs? If they are, and they are working properly, they are worth considerably more than what you paid for them. However, based on your other recent posts, I'm thinking you weren't aware of the differences in the many versions of the PS3. So I'm just going to guess that you didn't find any models capable of playing PS2 discs. Fortunately, those are still good deals for any model of PS3 assuming it works properly.
I keep mentioning "if it works properly" because that generation of gaming consoles (specifically PS3 and 360) was arguably the least reliable generation of gaming consoles of all time.
