If you really need one urgently, may I suggest the Picollo Control Stick. It retails for $39 at the TIEstore. Also, keep an eye on TIDeals. They come up with really good deals. The Picollo sold for $33 last week. It is now sold out.
I think I can help you here. You probably have not set your boot switches properly. I went through the same process
