My friend said they are like 1500g.Does it cost that much??

firstly, this really depends what server you are on. I have heard people saying Aries is a overprice server!!! sadly I am in Aries... >.<

And actually, transformer needs quite some original rubber, 6 copper ores and 5 hard plate. Although org. rubber, copper ores and aluminium ores are pretty easy to get, it still requires time. You also need quite sometime to make it... so 1k5 is not really expensive

wow...guess i better buy some XD
