Through previous ownership of proxies in the past, I've found that bandwidth is a very important variable. Although your plans have quite a bit of bandwidth, if one gets big it can need a lot more bandwidth. Maybe the last plan should be for big proxies that require the most bandwidth. I've owned proxies before that need around 600GB bandwidth a month, I know thats really edging onto getting a dedicated server, but maybe a plan with 300GB? Just a thought
Nevertheless, looking good guys Nixism never stops amazing me
