I've been in the keyboard hobby for over 8 years. I have 55 keyboards. Yeah, kind of obnoxious. To be fair, most are actually not particularly expensive, though I do tend to buy GMK keycaps almost exclusively lately, with some Drop MT3, PBTFans, Keykobo and SWG thrown in. Which means several of my completed & assembled keyboards have keycaps that were more expensive than the keyboard itself.
I've got 10 of them at the office (nothing terribly expensive goes just in case they disappear) and the rest at home. Six in current rotation are Keychrons - an original version Q1, an original Q60 HHKB, a Q5 Pro, a Q5 Max, an R3, and a V3 (outfitted with silent switches for when I need to be quiet). I have a few other Keychrons which have been retired and shelved as I'm unable to make them sound satisfactorily and/or they're entirely superfluous at present and have been replaced with better ones. I do have a Q6 Max which is decent and looks good (with KAM Superuser keycaps), but doesn't get much use given its enormous size.
The rest are made up by a few Nuphy offerings (two Gem80s, a Halo65v2, a Halo75v2, a Node100LP, and a Node75HP — good office boards), a batch of NovelKeys ClassicTKLs in various colors, two Qwertykeys Neo70s (sale too good to pass up), a Neo98, many KBDFans keyboards (Pavlov65, Boop Redux, Dusk67, Tofu60 2.0 HHKB, Tofu60 3.0 WK, Tofu65 3.0, TofuTKL, Agar, Agar Mini 40%, Athena75 and two Athena1800s), a Vortex M0110A, a Monsgeek M2, a pair of Smurve80s, a Bridge75, an Evo80 and a Crush80, a Command65, a couple of CannonKeys Bakeneko65s, a Tess65, an Omnikeys Bauer Lite, a Keycult-KeyMachine 1/65 Ext. 2048, a Keycult 2/65, an iNN Studio Flo-AT, an IV Works Umbra60 WKL, a GDK Labs NV70, an AKB ORG2 65XT... and others that I know I'm forgetting. Plus three others currently on group buy pending (eventual) delivery.
Some of those were expensive, but the majority are actually mid-range boards. Not really interested in the super-expensive ones — law of diminishing returns and all that.
I used to like to recommend Keychron Q-series and V-series as kind of a gateway drug, but their QC issues over the last couple years and their increasingly horrible customer support has really soured my experience. And with careful selection, there are other prebuilt and barebones offerings that can be just as good if not better. The one I often recommend currently is the NovelKeys Underscore edition of the ClassicTKL is a prebuilt TKL with a very high quality injection molded body, actual GMK CYL Classic beige keycaps, well-tuned Typeplus stabs, and their own custom smooth linear switches (NK Classic Blue) for $199. Full, native QMK/VIA supported with source code available. You can find cheaper, but not as well built and not with real double-shot GMK-branded keycaps. Their customer service puts everyone else to shame. And while parts are manufactured overseas, the small company itself is based here in the US (West Virginia). Good group of guys. And they're a Keycult vendor, FYI. The various Qwertykeys offerings are excellent, too, in terms of the value to quality ratio, but they are based overseas if that matters to you.
