Recommendation
I own a Pro-94 and only use it for listening to Skywarn frequencies.
If you invest in a digital scanner, I would do your homework and see the various brands and features.
Yes, some of Galveston County is analog, but there is also digital radio traffic.
I have no problem listening, and recording Galveston when Mardi Gras rolls around. In fact, I have been going there for over twenty years listening to the action. I highly recommend a Uniden 436HP. This radio lets you (like some other Unidens) put in the zip code and go. You might need to change various services types (agencies like EMS talk, EMS tactical, etc.) in the menu, but this radio picks up Houston Phase II as well.
The technology of scanning radios has dramatically changed since the Pro 94 was around.
