Replacing laptop keyboards with an original spare part is surprisingly simple and straightforward if you're moderately competent and have a steady hand. It's not something everyone would be willing, or able to do of course, but if you're willing to give it a try and the original keyboard is to your liking, then it's not quite as daunting an option as it seems at first.
I've built my own desktop PCs since the 90s but I was always wary of the internals of laptops until my own laptop keyboard went the way of the dinosaurs. I bought my HP Pavilion G6 in early 2012 and in late 2016 the keyboard stopped functioning properly. I bought a couple of plug-in and wireless keyboards but it wasn't a viable solution, so I investigated repair options. I could get it professionally done for around £70-80, buy a compatible spare for around £7 or an HP original spare for £20. I found literally dozens of guides and instructions online and a number of videos on YouTube that showed exactly how it was done so I took the plunge. I didn't even have to open the laptop up and it took me 20 minutes. Still going strong today.
Since then I've done it for a couple of other people too, and in most cases it's a quick and easy job. Recently I had to open the same laptop up and disassemble it to clean out the system fan which had got clogged up with 7+ years of dust and gunk, but even that was done with the help of comprehensive video tutorials on YouTube & Vimeo. In the process I replaced the Hard Drive with an SSD and the machine is running better than the day I bought it.
Like I said above - it's not an option for everyone, but if you like the feel of the original keyboard it's worth looking into. Even if you don't feel up to doing it yourself, you may know someone like myself who's willing to to do it for you for a pint and a smile
Incidentally - I only just bought a new laptop - yesterday in fact. The old one is still in service as a browser/word processor, but I needed something with enough oomph to use for video work that would at least match my desktop. It doesn't have the separate bays for HDD & memory that the old G6 does, having a single back panel, but again I found guides that show it's dead easy to upgrade. Just take 10 screws out of the base panel, prise the panel off with a "spudger" and everything's right in front of you. Coincidentally, it's another HP machine, but the internal design is much better than my 7 year old machine - you can clean it without having to disassemble it all, just pop off that base panel. Ironically - keyboard replacement on this model would be less straightforward
