I bought mine from this site
http://www.webcon.co.uk/ Dont think its genuine weber although it says it is, mine did not have weber printed on the casting where my standard 32/36 did.
Very cheap for a brand spanker and havent had any issues after 3 years driving every day. Jetting will be very wrong though but im sure you are aware of that. You may be able to let the company know your engine and they could jet it to be a bit more driveable before you get a tune done.
