Pretty funny, 1000 will not get you like the most hyped keyboard or Flex board like a TGR or Keycult but will cover some of the best you can buy if you missed a group buy.
GMK keysets are worth anywhere from $170 to like $400 on average, this is due to sets being ran in Group buy and GMK having to make them which as of writing this is up to 2 and a hlaf years wait from a GB ending
You can see ""GB End" and "Shipped Date" here
You can actually make a profit on quite a lot of stuff you buy in the hobby due to this fact stuff is either ran in limited numbers like boards or take ages to be made and shipped or just rarity like Artisan keycaps.
I like a smart consoomer refuse to buy any after market prices on anything but will join Group buys or try my luck at raffles on boards and artisans I like. I have a board I was lucky enough to get a spot in the GB for was about $300 or something and seen them sell from anywhere from 2k to 3.5k as of recent. Not that I sell much or buy much but I could come out much richer than the money i've put in.
