Thanx for your help Stylishkiller!
I dont need a VERY EXPENSIVE one right now as Im just an ENthusiast and wont be tuning cars very frequently. Just wanted one for Personal Experimenting.
I found one which I've mentioned in above post. Its for 50$ AUD (Australian Dollars). The company is DIGITECH and part no is mentioned in above post.
Thanx ! Do let me know if u get more info.
