Lo 1st post so noobish

I am looking for help with the following itams that i have and wondering what to do. 1st i grew up dreaming of owning a SF2 cabinet, now i do but have some issues.
I have a SF2 cabinet with game and busted Hanatrex MTC 9000 (not exactly sure if its busted or not it flashes in all corners then nothing once i saw a rom loading screen then flashes and then nothing).
I hear sound and thats it nothing no the picture on the screen, that is what i have not working.
I got a broken Sony Trinitron tv that will fit in 21" but sound doesnt work, im trying to get an Xbox and maybe put a Hard Drive in it and get Mame onto it with the Dual Xarcade controllers mounted to front of cab. Problem is im very poor with little ones to feed

So here is quandry, do i go with the Xbox and just have a cab to play it on?
Do i try get the tv working from the Jamma game?
Afaik i know all the buttons on the cab work ie stick and buttons so with a budget in mind im not sure what to do, the cab needs some love and cleaning but other than that its a solid cabinet.
What do you guys think i should do?
i found a site linked from here that sold a sort of jamma to tv thing not supergun thats too expensive for one game, was something else a US site but i cant find it anymore.
Thanks
