I received my razer blackwidow 2014 from the amazon marketplace used yesterday and the 'T' key doesn't work. Unless, I press the key, bottom out, and apply excess pressure to the bottom of the switch. This makes typing extremely tedious as I used one of the macro keys as my 'T'. It even sounds different and doesn't have the 'bump' that the Razer Green switches are supposed to have. I know that these switches are cheap and aren't a part of the #CHERRYMXMASTERRACE, but I gambled anyway. I emailed the seller already and they said they will refund my payment, but I was wondering if there was a fix I could do without soldering. If not, recommend me some suggestions for a keyboard around $80 usd that have blue switches.
CMStorm Quickfile line.
TT exports Poseidon line, though the Z uses Khail switches if that matters to you, kahil's clones are fine by most accounts.
Rosewil RK-9000 V2
Ducky Zero.
It is also worth taking a look on sites like reddit's /r/mechmarket and AliExpress as Asia seems have a larger mech market than western countries. There is also TaoBao but you will need to use a proxy to order as it is all in Chinese and only ships to China, but there is cool stuff there, reddit has more info on how to order from them if you want to look into it.
The TTC switch iBuyPower mech gets honorable mention as a super cheap mech. Though it uses red switches and unproven, are clones of MX with no reason so far to see problem with them. There is all a bleu switch version from iBuyPowers OEM MEK https://gamdiasgaming.com/product/hermes-lite-mechanical-gaming-keyboard/
