Welcome! Sounds like the fun is just beginning for you, I suggest you stay away from watches whilst you still can! :D
I think defining watches as Low/Mid/High is probably a bit subjective. A mid range watch to me might be low end to someone else. As for the types people go for, you'll see pretty much everything on here, though I would say people tend to keep their distance from the fashion brands/styles.
The good news is that you can get a very nice watch for very little money, for example our host has some superb pieces http://www.timefactors.co.uk/precista.htm and I'll be picking up a PRS50 at some point this year! I would also recommend the Seiko monsters (black or orange) as they're a lot of watch for the money. You'll also get a lot more watch for your money if you buy used and the sales forum here is a good place to to start.
I hope you find something nice!
