It might be $10-$20 cheaper for those few sites that still have a very limited stock (remember most stores are out of stock on GP32 an will probably only be getting BLU's in) but I doubt it will be much more (if any cheeper at all) let alone $50.
Its actually more expensive on the Entware store or something since they are harder to find. I would have thought they would sell them cheaper to empty stock.
