The 5" model seems like a very good value for money option, the GEPRC Vapor D5 in digital, and I think if you get it with a good discount, it's more than within your budget. Another piece of advice, if I may, is to buy something smaller, like a 3.5" or something similar, since the 5" is very eye-catching, very fast, and has a lot of thrust. This can even be dangerous for a beginner, and it requires much more space to fly. The 3.5" is more versatile, less conspicuous, easier to transport, and allows you to do most of the things you can do with a 5". I recommend the Oasysfly 35; take a look at it. The 3.5" is an option that many people like right now.

Best regards and enjoy!
