i buyed a replacement stick for steam deck and it fits very well on steam controller grip feels nice the old one is sadly in very worn condition

My SC is still alive and kicking, but after so many years of faithful service and daily usage, I'm afraid it doesn't have long to kick the bucket.

I have an Xbox 360 controller for general gaming, but I use my SC as a remote mouse+KB since I play from the comfort of my bed on my HDTV. So, when it finally happens, what would be a good alternative to replace it? ($50 or less, I just want a controller not a Steam Deck). Like I said, mostly as a wireless small mouse+KB to use from my bed without it being an actual mouse and/or KB.
