I wrote to Arnold some time back and he was polite in his reply. I needed something a little stronger than usual for work related use (something Arnold didn't seem too keen to assist with) and I work in the Film Industry in a well known VFX firm so my needs were legitimate. I ended up buying some lasers and 532nm safety glasses from Wicked last week. They were shipped on Monday from China and arrived on Friday in Australia. Speedy service and the lasers work flawlessly although I've only had them for two days.
I requested a few different lasers including a <110mW and a <5mW although the <5mW is far stronger than I was expecting and appears to be closer to <25mW. They may have sent me a stronger module intentionally (I did ask them to send the strongest output models available) although I can't really complain, can I? Construction and quality appear quite high. Emails to and from Wicked were responded to very quickly, even after the delivery of the goods (which is rare these days).
Just put an evaluation gallery together for the new lasers here:

People speak well of Arnold so I'm going to have to say that he's certainly well respected here in the forums and elsewhere on the net. Also, different locations in the world have different restrictions for importing lasers so see what your needs are and make a decision based on who is likely to be the most reliable based on your needs. I can vouch for the Wicked guys since they played by the rules from the beginning which is a relief... I feel very uncomfortable purchasing with a credit card online, although they accepted paypal which is good.
