Yes. I know about them.
Let me sum it up:
-3+ month wait after ordering, never heard a word.
-Unanswered emails.
-When the lasers arrived they were horribly misaligned, I had to realign them myself.
-One of them claims to have a 200mW red module; metering it gives me 3mW. (this is the 'magenta'.)
Good in theory, but basically all they did was provide me with a place to start from, after much difficulty.
I've got at least two friends who placed orders with them who had the exact same experiences. One had to send back a 650/405 unit 3 times, and just finally gave up and resorteed to fixing it himself.
I know nobody else is really selling ready-made mixed color lasers, but really, don't give into the temptation to order from them unless:
-you're prepared for a several month wait,
-you're prepared to realign the units yourself (and every time you use them...)
-you're not worried about customer service or responses,
-you're willing to pay a lot of money for essentially a case and some dichros and some off spec lasers.
I made this mistake early on, before I got to LPF. Hopefully, you won't have to. I'd review them, but it'd make it look like a trash piece. I don't think I could be neutral after my experience with Sunclan.
