It's really not that bad, for example here are some keycap set you can get:
$11.50 - Tai Hao ABS Double Shot (Elton's Group Buy, $9 Full Set + $2.50 Spacebar)
$33 - Vortex PBT Double Shot Italicize Fonts (Feng's Groupbuy)$49.50 - DSA PBT Blanks (Signature Plastics, $21 Base + $19 Mod + $9.50 Tenkey)
$50 - WASD Keyboard ABS Laser Etched
$51 - Ducky Thin PBT Laser Etched
$55 - Imsto Cherry Thick PBT Blank (Groupbuy)
$69 - Vortex PBT Double Shot Bi-Color Version$75 - Imsto Cherry Thick PBT Dyesub (Groupbuy)
$78 - DCS ABS Double Shot (Signature Plastic, $60 Base + $18 Tenkey)
$85 - BSP PBT Blank (Only 85 Key, No Spacebar, Originative)
$100 - Cherry ABS Double Shot (Originative)
$105 - Raindrop ABS Double Shot (Signature Plastic, $90 Base + $25 Tenkey)
$120 - GMK ABS Double Shot (Ivan's Groupbuy)
$130 - BSP PBT Dyesub (Only 85 Key, No Spacebar, Originative)
It only feel expensive if you compare this to the first Vortex Double Shot PBT set. But then again that's cheaper than EVERYTHING else except Tai Hao so it's kind of unfair to compare to that.
If you just take it for what it is, for a Double Shot PBT I think it's good price.
EDIT: Fixed BSP PBT price. Thanks Photoelectric.
