Mac OS VPN connection client

I need a VPN connection software similar to this one but it will be for Mac OSX: [login to view URL] I need the Mac version of this software with the same functionality. In simple software does this: 1- User enters username and password 2- User chooses the server address 3- Software makes a PPTP VPN connection to the given address using builtin Mac OSX PPTP VPN client. 4- Software reads server addresses from an external URL. My maximum budget for this is $100. So please bid reasonably.
