How to capture video from a PS Vita?

I've been exploring the idea of streaming from a PS Vita which should be a lot easier than it has been. I currently use a stationary camera mounted over a desk to do so. I have read about a service to add an HDMI port but I cannot find anyone who has used this service and has had success with the results to justify the cost.

First time I hear about a HDMI mod, but there is one that lets you get the video through a mini USB 2.0 port, though it's not the cheapest thing to get. Costs roughly $200'ish just for the mod itself. That's not counting the Vita.

Quality seems to be alright I guess. Don't think we're allowed to link to the site directly, but if you google for "ps vita capture card" you're bound to find the thing I'm talking about.
