The Logitech, Corsair and CM TK all are made by the same OEM as far as I can tell, and have the same mixed size bottom row and odd sized spacebar. The Tt Posiedon also has a nonstandard bottom row, but they use all easy to obtain key sizes.
All the keyboards made by iOne will have the 1.5 1 1.5 6 1.5 1 1 1.5 bottom row arrangement. iOne build quality ranges from terrible to OK... rebrands include stuff from Razer, Gigabyte, Func, Roccat, Tesoro, and many many more.
Most other brands use the current standard which is 1.25 and 6.25 keys for the bottom row. If all the control, alt, windows, menu keys are the same size you won't have issues with swapping keycaps in general.
Perusing ncix if I were you I would pick the Ducky Shine Zero (DK2108SZ) which is less expensive version of shine without all the flashy led effects and is currently on sale. Or, if you could do tenkeyless then CM Rapid I would be another good pick.
