Burner problems are not unique to Pioneer, catman! The highly touted BenQ 1640, for example is being RMA'd by buyers sometimes three times before getting a fully functional unit. Read the forums. As long as rock bottom price forces manufacturers to China to compete QC will remain an issue.(I'm really speculating here).
Stop snivelling, do your homework and get on with it!
Many people here are VERY helpfull, believe me, but you'll need an attitude adjustment to take advantage of their experience.
