PSP Spare Power Adapter

So I've got a bit of a long story that leads to a minor request. I had a fairly old Sony DPF-D72N digital picture frame. For some reason its power adapter went bad and I couldn't use it. But then I discovered that the PSP 2000 power adapter works great with it. But... I also like to keep my PSP powered up because I use it periodically.

The problem is that finding an actual official PSP power adapter is damn hard, or expensive. I tried a couple of the cheaper knockoffs, but they all went bad in less than a week. I thought about getting a knockoff DPF-D72N compatible power adapter, but they all seem like knockoff or with a really short cable.

So, I was wondering if anyone here had a spare official PSP 2000 power adapter they'd be willing to part with for some price.
