exactly - sorry about your experience on Betarigs - I have rented from them also in the past and it's hit or miss - especially with the one's that say "they're monitored' then YOU have to tell them their machine is down and not mining. My experience has been that most of the renters there will give you extra hours but that does not make up for lost opportunity when the difficulty was low when mining started. I grabbed two blocks in the first 5 minutes before network hash skyrocketed. IMHO - the value they have set on the coin right now warrants about least 80 to 100 Gh/s to make it much harder to get - but that's the investor in me speaking. My pool miners are thrilled the network hash is as low as it is because people with 4 and 5 Mh/s are still getting a piece of the pie.

ps: I got in very early, but it's still painful to see people accumulating coins with such little hash.
