You will be looking at £2000 + VAT for a proper LPG install. You will lose your spare wheel and/or some boot space. You will invalidate any outstanding warranty and you could make the car harder to sell on, so you need to be sure you are happy keeping the car for a long time. Your performance and mpg will be reduced slightly running on LPG.
This is all spot-on stuff, although the price can be kept down a little if you shop around (best to use garages with a recommendation though). I`m unsure what the JTS system is exactly (??) but the garage that did my car does 156 twinnys happily enough. Regaining your outlay can be calculated by working out how many miles you do, how much the conversion costs and how much you spend on petrol. The running cost of the fuel will be about 2/3 that of petrol (although its a bit better when the petrol prices are higher like they are now).
The price of the fuel doesn`t seem so much of a problem - I found this on the Customs and Excise site and it shows thattheincrease in duty will be small for a while. Of course, nothing stops the Government changing their mind, but thats the same for anything.
"Following a consultation on how best to ensure that future support for road fuel gases continues to reflect environmental and other policy objectives, the 2003 Pre-Budget Report announced that the duty incentive for LPG would be decreased over time to a level more commensurate with its environmental benefits..."
"Budget 2004 confirmed that the LPG incentive relative to the main road fuels would be decreased by the equivalent of 1 penny per litre in 2004/05, and by a further 1 penny per litre in both 2005/06 and 2006/07. This means that the rate of duty for LPG will be 13.03 pence per kilogram from 1 September 2004, equivalent to a duty differential with main road fuels of 40.70 pence per litre."
If you are really interested Calor do a good site on Autogas and I can let youknow of two garages that have Alfa experience for fitting that could give you more advice on cost and tank sizes etc.
