Just get some well-grown stuff... I find people put too much emphasis on strain, myself included sometimes. I've had one of these "untouchable" strains before... probably the one you're alluding too... and honestly I've gotten equal or better many times. Granted, it's good bud but you can find a lot of good bud out there still. Not all vendor bud is bad!! True, it's got a greater chance of being harvested early or having other problems since the vendor doesn't have to stand behind his/her product as much as a dispensary, but there's some good stuff out there too!
