My setup will have over 15 ghash and no i think im pretty early considering that this is brand new and most people do not even know what a bitcoin is.
It will require semi-professional planning though, even if you run it in some basement.
I have max. capacity 16ghash/s and already down by 2 due to random hardware failures and waiting for RMA's.
Failures do happen statistically even if your operation is perfect (clean 80+gold PSU's, well ventilated, etc.)
Every day a part of the system is down you lose money. So a faulty ram stick or DOA gpu can become very expensive over 24 hours.
just buy what you can afford. In this stage, even .5/day is pretty good. I just bought two 5830's that should get be around 200-300mh/s a pop. Probably closer to 250 or so but still. 500mh/s is pretty good to start with.
OR you can do another thing - just buy BTC and hold onto them for later.
If you can't afford it... you can't afford it
