The only reason people get a diesel is because they either do loads of miles (which you dont) or cant afford the petrol or aren't really that into cars. Why would anyone want their car to sound like a tractor and finish revving at 4k when you can have a petrol?
As long as I can afford it I will be in a petrol.
What category do I fit into then?

My mileage has dropped since we moved offices to below 10K and I'm safe to say I'm very much a car enthusiast and I could afford the petrol if needed
FYI mine revs past 5K RPM

To answer the OP's question. I did consider an ED30 before buying my Audi TDI. Having owned a diesel for over 4 years I couldn't bear the thought of having to fill up twice to travel the same distance on one tank of diesel.
Whilst I'd love the power and the potential of the ED30, for me in the mid range, a diesel has enough grunt to make short work of any over-taking manoeuvres, and with a remap you do have to pay attention as you might find yourself a little close to the bumper as you pull out....
In this day and age, with the amount of traffic and the state of our roads, diesel is just as quick across country as its petrol equivalent. There are speed limits remember

Also, fuel prices are only going one way......
