Good company compared to what? I've bought lasers from a lot of companies, forum users and ebay sellers. So far DL was the company that left me the most unsatisfied.
For crying out loud, back in the day I received a full refund from DX from a DOA item and they didn't even ask me to return the item.
To each their own. If you don't mind gambling $400 go ahead and order one. 589nm is surely a nice color
Edit: it's not just the hassle of sending it back, it's the risk that they'd scam me like they did with rhd (link is on OP).
