TX here too. My 16-yo just got his learner's permit and that can't be done online. Many locations don't have available appointments for months. Some, such as in SE Texas, have same day appointments. We ended up driving over an hour away to get a same-week appointment.
I had a classic 101-key Unicomp Model M that I purchased while they were apparently having quality problems due to worn out tooling. The keys felt different than my real Model Ms and the spacebar frequently stuck. They've since refurbished the tooling and I hear the quality is back to the high level you would expect.
For me though I just chose to retire the Unicomp and refurbish my real Model Ms. I bought three about 20 years ago from https://www.clickykeyboards.com/ and sent them back last year. They're as good as new and they feel so good to type on. Plus I don't have those damned extra keys the "New" Model M has.
