You should be able to get a nice, new band for that price. Of course, pre-loved is usually best (more bang for your buck) but, if one doesn't show up, you can still get something nice.
I have a very fine rose gold band I don't wear anymore. It's about 1.5mm wide. I'd need to check the size but it may be closer to a 7. Do you want me to find out?
I'm in Melbourne so easy to post etc. if you want a photo, you can contact me through Looptroupe and I am user JR0147.
