beam combiner unit

Hello , I just thought if any one is interested , I would post this link -"http://www.princetel.com/dl_bc4.asp?gclid=CPWI-5mNmaYCFUdrKgodTma9oA". It is for an up to four laser laser beam combiner.
I sent them an e-mail to inquire about a price. If too expensive singly , maybe a group buy then.

That thing is for 635nm and larger and can only combine two identical wavelength diodes, which we already can do with a PBS. And it's going to be VERY expensive, even in very large quantities.
