I've been using wired mechanical keyboards for about 15 years so I can't recommend a wireless model, but Ducky makes great, reliable, entry-level mechanical keyboards. I've mostly used Ducky and I've never had one of their keyboards fail in any way. Glorious also makes great keyboards, but based on my perception of the build quality, I have a feeling their cheaper keyboards might not last as long. I'm currently using a Glorious GMMK Pro and it feels very solid.
