I wish I knew where you we looking! I paid $100 for 32GB (the biggest at the time) and I haven't seen 64GB for that price, yet. Plus I've read that they were easily corruptible. Of course, with the Switch on the market, my Vita may as well not exist now.
Yeah, the 64gb Vita cards have a bad reputation. It's why I never bought any. I would have loved to have had them instead of the 32's, but it wasn't worth the risk.
