Hi sifus,Just a few questions as below as i want to get a scanner for my E39 2001.a) What is the best scanner for the E39, the PA soft 1.4, the INPA or the GT1?b) What are the main differences in between them ?I saw some advert for some GT1 with DIS V57 which cost about USD 400.00 complete with all the stuff. worth to get it :topr better off with something else cheaper that does the job?I read from the Group Buy that the installation for PA soft on windows is tough with technicalities. I am not a computer geek. haaha. I read that the GT1 is simple and straight on the go once installed.CheersLW Loh
