zeOrb, right now your only choice is to get an Oculus DK2 and a Hydra, if you really want to start immediately.
I doubt you can get a Vive currently, even from Ebay. Valve is giving out the dev kits for free, probably with some kind of contract preventing resale. But really, who would want to sell a Vive right now? 
Alternatively you can wait a few more months for the consumer release.
