regarding ur question?
well, ps3break is a chinese clone of the original (but delayed, not yet shipped version of modchip). (i'm not sure yet if its upgradable softwre wise)
we're ordering Minimus AVR. it is custom built for the only reason of using as USB programming like using with ps3. it has better components and its flash is upgradable to newer versions of the hack.
because hackers are improving and releasing newer versions and patches for the hack, so reprogrammable boards like the MinimusAVR are the best future proof way to go.
