Playstation TV

I can get a PS VITA TV (or Playstation TV) for about 50$ with a chinese controller. I mean, PS TV for 35$ and a 12$ controller from China.
The controller is supposed to be PS3 compatible with bluetooth, so it fits the vita?
And anyways, whats my point. I have a mint PS1 Slim, but dont have a controller and power adapter, wich costs almost the price of the PS TV console, lacking the pad. And I somehow lost my psp (cant find it lel), i had a few PSN games, so i could play them theoretically on the PS TV.
And, I wanna know if i should buy a PS TV, PSP or PS VITA (wich is pricier). Anyone use this console?
Oh and, impressions on the PS3 controller knock offs (http://goo.gl/9Vt9N5).

So, 50$ for a console playing PSP, PS1 and some PS VITA games? Or should i go back to my PSP or just get a PS vita, for portability (my phone doesnt have much games :D I could use the Vita sometimes when i go somewhere, put the TV with the pad would fit my backpack anyway)

So any impressions guys?

again, the link to the controller http://goo.gl/9Vt9N5
