Yep, tried ebay and they have tons of non-RGB versions and I got one of those for the time being.
I found a 4-slot RGB HB Bridge on ebay Australia, but no 3-slot.
Pretty much looked everywhere I can think of and have only been able to find one. Problem is, it's at a PC store in Manila and I'm in the southern US and it's already kind of pricey without considering shipping.
