The 20GB PlayStation 3 will no longer be offered in North America, leaving only the $599 60GB model the only one available for the market. In Japan, however, the 20GB model will still be sold. This gives a choice for gamers with little budget.

The Japanese 20GB PS3 is one of the cheapest versions of the console worldwide. With its price cut even before the console launch, the 20GB PS3 currently costs 49,980 yen, or about $421. Thats indeed the cheapest at present since you cant find any Ps3 for such price anywhere in US.
