I'm starting a t shirt design/printing company in a few months and looking at accepting Bitcoin as payment but I'm also struggling to work out how to tier it, do I have a fixed price ie 1 BTC or do I link it to the £10 GBP price I'll be charging and people will have to pay the fluctuating BTC price?

Yeah I've been looking into buying another couple of rigs around winter time, putting them into the attic then fitting some basic tubing to vent the heat to other areas of the house. Should cancel out the electricity bill they run up hopefully 

I agree, I've been crunching the numbers and have decided against buying a new dedicated mining rig and just modifying my existing gaming rig. It's cost me about $200 and will bump me up from 120M/hash to 700ish.

The fact that I have four months left on a housing lease where I have unlimited electricity helps make things a bit more profitable too 

I was interested in day trading under the bitcoin model but I haven't looked into it much, where do you trade?

Yeah, GeForce cards aren't much good, I just sold my two 8800GTX cards and bought Radeon 5850 Extreme cards.
There's a comparison table of all the M/Hash's in the Wiki https://en.bitcoin.it/wiki/Mining_hardware_comparison

Also I have read that yes the Bitcoin faucet is dry but some online foundation that accepts Bitcoin donations has decided to donate them all back to Bitcoin faucet to try and strengthen the currency, so hopefully that will happen soon.
