What is the absolute best battery grip for the Canon 90D that isnt gonna cost me an arm and a leg like the official one? I have been using my 90D for a little over a year now mostly for birding and wildlife shots out here in Oregon and carrying it around with a heavy Sigma 150-600mm lens is starting to cramp my hand up pretty bad. Plus my batteries keep dying right when the light gets good.

I am planning a big trip out to the Rockies next month so I really need to get this sorted before then. I did some looking around and obviously the Canon BG-E14 is the proper choice but I just cant justify spending $200 on a piece of plastic when I still need to buy more SD cards and maybe a better bag. I saw the Neewer grip on Amazon for like $50 and it has okay reviews but then I saw a few people saying the buttons feel mushy or that it actually drained their batteries while the camera was sitting in the bag. That sounds like a total nightmare if Im hiking for miles and find out my gear is dead.

Then there is the Vello grip which is more like $80 or $90 but is it actually any better than the cheap ones? Some forum posts say the weather sealing on third party grips is basically non existent and since I live in a rainy climate that kinda worries me. I want something that feels solid and wont flex when I have that huge Sigma lens mounted on a tripod.

Is the build quality of the Pixel or Vello brands worth the extra cash over the super cheap Neewer stuff or should I just try to find a used Canon brand grip on eBay? I really want to stay under a $100 budget if I can but I also dont want to risk my camera body getting short circuited by a cheap knockoff. Has anyone here used a specific brand for a long time without the shutter button failing or the rubber peeling off...
