OK i know this is going to break ur bank. But like i said, GH is only bad for your wallet if you are bad at controlling your spending
First get this,
http://www.ebay.com/itm/Cherry-MY1900-PS-2-POS-Keyboard-TESTED-/150697379982?pt=PCA_Mice_Trackballs&hash=item231643888e decent price, except u'll need to clean it and hopefully it is not too worn out. If you have problem with the PF1 2 3 key whatever... then maybe it is not for you. But if u are only going after the alphas then u should be good.
Second, depending on what you want to do... it seems u want to have a black surround to your white keys... then u'll need to spend more or a lot more to match the profile of ur cherry keys. U'll need to find a black donor board on ebay, which is easier than finding a white one. or u can ask around here
If u just want to replicate white beige cherry double shot, ur life is a lot easier. go to moogle kit group buy and order a kit to replace the incompatible keys from cherry corp. The incompatible keys include: modifiers (alt ctrl etc), space bar and caps lock or more depending on where u harvest them from.
Regarding to the key compatibility, If you go for a full size G80 POS black board then u'll only have space bar that is not compatible. However u'll spend a lot more to get a hand on those. If u go for G81 black double shots, again u'll need to get a black moogle kit to make things close to perfect.
