Well you can't go wrong with Swaro's. You might want to think about rangefinder bins but I'd absolutely recommend you to spend some time peering through whatever you shortlist. I bought mine as a work leaving present about ten years ago and the shop very kindly allowed me to stand in the doorway searching shadowy areas up and down the street. I went with the ones which gave me the best results in the deepest shadow. I figured this would help in woodland conditions and interestingly the best result did not come from the most expensive.
Have a look at swarovski 7x42 slc around that kind of money really good binoculars, others you might want to look at include the leica trinovid range I have a pair also in 7x42 excellent glass, again you should be able to pick up a good pair for around 500 or less. I also own a new pair of zeiss hts in 8x42 and while they are truly brilliant especially in the low light, for less than half the price you really can't go wrong with any good used swaro,zeiss,leica other people on here also really rate the minox bino's though personally I have no experience with these, but with your budget you should end up with a top glass which will serve you well for many years.
