Don';t know if the PRS trem will fit the rout, but i think it comes in black and it's the best non locking trem on the mark IMO. Other than that, there's Callaham, don't know if he does wither 2 pointers or black though
I think this Gotoh unit will fit. It's not "black black" though, more a sort of "cosmo black" or "black nickel" kind of look:http://www.wdmusic.co.uk/product/Contemporary_Two_Pivot_Mount_Block_Saddles_Tremolo_System_510TS-FE1BCrazy price at WD, but I expect you can get them cheaper if you shop around. I have the six-hole version of the same bridge in chrome and I'm sure it was nowhere near that expensive.
I recently got one of these for a project http://www.ebay.co.uk/itm/HIGH-QUALITY-TWIN-PIVOT-POINT-STEEL-BLOCK-FULCRUM-TREMOLO-STRAT-ETC-BLACK-/170706933897?pt=UK_Guitar_Accessories&hash=item27beed1889#ht_6108wt_1396certainly seems sturdy and well made.
