My professionaly done conversion (BRC Sequent 56) cost just over 2 grand (£1850 + VAT) in May 2008 (nearly 2 years ago).
Now, when I bought the car I had factored in that cost as part of what I considered to be the "total" purchase price, but that is just my way of looking at it. So I consider it to be saving me around £100 a month in cash outlay on fuel. My monthly mileage has dropped considerably in that time .. when I first had the install done it was £200 a month savings.
Others look differently and go on "how long to pay for it" considerations. Well my conversion will, according to my calculations, have paid for itself in 3000 more miles... total of 24000 miles..
I bought the car with the intention of converting it and keeping it for as long as possible, with luck in excess of another 10 years.
That was the reason for the "professional" install .... as well as my very limited DIY skills

I did a LOT of research and projections before making the decision ... but I have not a single regret that I went for it ..

DIY is obviously a far cheaper option, and with the accumlated skills of the forum, if I was to be converting one now, that is the way I'd go..
