G19 is a ricer board, Logitech is practically stealing your money for how much they charge for it relative to how much that board costs to make.
If you really need a stupid LCD on your keyboard I can't help you, but you can buy a keyboard that is 10x better than the G19 and still have money left over for a 2nd monitor.
That being said I wholeheartedly recommend the Steelseries 6Gv2. Its Cherry Black key switches are thus far my favorite switches at least for FPS gaming.
If macros are a must then you might want to consider the Razer BlackWidow, it has mechanical key switches like the 6Gv2 although they are the Cherry Blue switches which provide a tactile bump and auditory click at the point of actuation. These switches are considered to be some of the best for typing, but I have found them suitable for gaming, certainly leaps and bounds more enjoyable/reliable than typical membrane.
The most expensive typical rubber dome membrane board I would recommend would be Microsoft's Sidewinder X4, which can easily be found for less than $50.
