473 on the cheap?!

so i was moseying around ebay when i spotted this
473nm Blue laser diode LBO optic assembly with TEC DPSS | eBay

i guess it's a cni optics assembly for 808->473. i was wondering what the actual logistics of making this work are. I have a 2W 808 just sitting around and if it's as easy as 1-2-3 im definitely going to get this baby.

This is just the guts of one of those BW Tek labby units that sell for $30 or whatever.

There are literally hundreds of the full labbies just floating around. I'm sure you could put up a "WTB" post in the BST section and you'd find a whole working 473 labby for the $45 they're asking in that auction.

I think I paid $35 shipped for my B&W 473.

ah ok thx
