Ask HN: Ning or WP based membership website?

Hi, I want to create paid membership based website, I have 2 options 1) Go with usual WP+Membership Plugin+Hosting Costs: Theme:$35, Membership plugin:$30 to $100, Hosting:$20 per month(Zippykid/page.ly) Pros: Customization, full control Cons: I hate WP (bcoz it gets hacked) 2) Ning paid membership addon Costs: $25 per month Pros: Peace of mind(no upgrades, no hacking) Cons: bandwidth issue, lots of -ve reviews, they take 3-4% of ur membership earning :( As usual I am confused what to do :) It will be great to hear from you guys
