razer Razer Blackwidow problem / Func MS3 alternative

[C3S4R]

Hello, first of all i have a razer blackwidow the first version no light no rgb no anything just the little logo on the bottom is lit in blue, btw the problem here is that the D key doesn't work when i turn the pc, comeback from sleep, etc. i have to spam the key like 20 times and then it start to work, also i noticed some doble presses on this key as well on the space bar and some other keys, i triedd blowing some compressed air to remove dust from the switches and also clean the keyboard but the problem persist.

 

In the mouse part i used tho have an asus GX850 and i loved it but the switches broke from the pcb so its mostly dead, i have some sort of a combination of a finger tip grip with a claw grip, and i wanted a comfy mouse that have support for the ring and pinky fingers (yup like a palm grip i know my grip its strange) i saw in a video the Func MS3 revision 2 mouse and i really love the design that's exactly what i'm looking for but is discontinued, so i want and alternative with a really good sensor with no acceleration, and the thumb buttons, also i play with an 5500 dpi so take that in mind and my budget is $90. (My english is not perfect i know)
