I'm thinking about maybe buying a beastx so I can give it a try. I might decide to replace the ZYX in the 600 but not really having any problems with any of them - just curious about the beastx.
You should give a try to this F03407 (BeastX clone): http://www.aliexpress.com/item/Free-...700702607.html
you wont be desapointed + price is sweet...
PS: My advice: Avoid free shipping option with lousy China post unless you ready to wait for 90 days (new aliexpress policy)
