Take your time mate, I've been lurking AW for 4 years, and only had my first punt (of 4 so far) earlier this year, and none of them have been great, each was a let down for some reason or another, I didn't know about this site during any of those so you already have an advantage that I didn't!
So pick and choose carefully, and what you can learn from here will be invaluable and will stand you in good stead, the great punts seem to be few and far between given the influx of zero feedback foreigners, but that should help you spot the good ones when you come across them.
