As for who is carrying the new v13, that is a very vauge topic. Not all Bestbuys are the same and some Bestbuys sell faster than others. Some game stores sell better than others and they get new pstwos more often than others.
You shouldn't be too affraid to buy pstwos, there are now fixes like summ0ne's fix which protects the laser pretty well. I've applied the summ0ne's fix to many pstwos and I have not had one return. Just use good media and burn them slow if you're going to install a modchip.
