The printhead of my Roland VS640i got damaged recently so I asked for quotes from local suppliers which came to the figure of around $2500-$3000 and that doesnt include any warranty, being the consumable item. Anyway, it feels really a big thing to shell our $3000 on something without any warranty. I looked into Alibaba and got the quote for around $1500-$1800 and that too without warranty, I have been procuring small hardwares from Alibaba which came our real good but again since the transaction is big so a fear has build up, I want to know if it is really safe to purchase hardware like printhead from there??
