If you mean the consumer rift you're limited to the big electronics shows for now, I'm sure that they have plans for broader consumer displays that we'll see in the near future.

But if you mean Oculus in general the Gear VR is an ok start (and widely available) but I'd recommend

(a) Get yourself to one of the many VR meetups that are fairly geographically distributed @ this point http://vr.meetup.com/

(b) Visit www.reddit.com/r/oculus and make a request for a demo in your area if you're in a less populated area.
