I certainly can't fault the Glock 19. Mine is a Gen 2, and I purchased it used, but had the slide refinished at the same time. It is one of the most popular handguns during this time of high demand, so no, you will not find any great deals. It is probably the most popular Glock model.
You aren't going to find much better deals on anything comparable, either. But you can look at the Springfield Armory XD. The XD(m) will be the more expensive version, so there are some deals on the original XD series to be had. It has a different grip angle, more similar to the venerable 1911, but you might like it.
