Newbie qc chinese supplier

Hi,
as new member on cnc zone, my request is not original or unusual but i'd like to receive some help before first ordering in China. After a lot of friendly mails exchanges about a laser cutting machine and cnc router, i reveived a suitable proposal from Jinan qichen machinery. Does anyone knows something about this company because i didn't find any advice concerning qichen machinery on any forum.As i received also proposal from G.Weike, please let me know some comments about these chinese companies.

Thanks a lot,

Bernd
