For the short term,  I would recommend betarigs as the risks are significantly less than actually buying mining equipment.  I personally see all investments into scrypt mining equipment right now as dead money as scrypt difficulty will soon increase at an exponential rate. With the advent of POS, we won't need to rely on miners for our security so I personally see no long term benefit to investing in hardware right now. It would be nice to have a stabilization fund sponsored, x13 multipool. That way the fund has a source of guaranteed income if a few trades went wrong.  It might also bring an influx of people to the coin as gpu miners are typically more invested into a coin when they have financial incentive.
