i saw the tv glow & binder recommendations

so, ive identified as agender since 2019(-2018?) and ive never really had too much of a problem with dysphoria - until a month or two ago when I first watched i saw the tv glow. (which was phenomenal btw obviously im not blaming the movie for my dysphoria lol just an unfortunate coincidence) but yeah after watching it i kinda tried my hardest to ignore it (i know, i know i see the irony) and recently ive just been washed by the realization that almost every trans person i know irl has detransitioned - even I've stopped correcting people on my pronouns or telling people im non binary (though im lucky enough to have everyone know me by my chosen name)

 but a couple weeks ago i rewatched the movie with my girlfriend and i just feel like i NEED to do something about this before it eats me alive lmfao. i need to "bury myself alive" as it were. soo i started looking at binder sales online.. but everything just seems so complicated and theres so many bad reviews of everything,, gc2b and wivov were the 2 i was looking at - mainly the full length tank ones but i think theyre sold out in my size - so i was wondering if anyone on here any advice?? i could just get a shitty one off amazon but i probably wont be buying another binder for a long time so id like to have one that'll last
