Which one to buy?X431 idiag or LAUNCH X431 V?

Last week, I bought a LAUNCH X431 idiag from autonumen.com,the customer sercie did help me a lot, because I registered but I forgot my user name, so I registered new ones, but none of them could not work.So I asked Joyce Gao for help.Finally, she gave me the correct user name and password from LAUNCH factory. 6.1 I asked Joyce how much will Asian and European software package will cost?She told me Asian softare package for LAUNCH X431 idiag is 699USD, European software package is 799USD.She told me if I will do multi car models, I should buy LAUNCH X431 V,because LAUNCH software is free update online for 1 year.That means I do not need to buy software alone, just need to buy LAUNCH X431 PRO, everything will be included, software, DBSCAR socket, an Android tablet, connectors. That sounds if I buy a LAUNCH X431 V instead buying Asian and European software for X431 idiag.
