Almost $800 here, but server costs are now up to $350 or there abouts. Not sure how many proxies around 100 also. 6tb of bandwidth used roughly last month.
But on a side note, the GBP (£) is so screwed when converting to/from USD ($) that my earnings are going much much further than before! A $200 cheque got converted into £154 of my currency, while 4 months ago that would have been around £95ish! Success.
