Should we migrate our VPN from MSCHAP V2 to something else?

http://serverfault.com – We bought a new Firewall a couple months back, a Netgear UTM9S, and one of the features we enabled is the PPTP VPN to enable access to SQL, Web and File servers for remote users. But now, after reading this Ars Technica article on MSCHAP V2 being broken I am wondering should we worry about this and turn off PPTP and enable one of the other VPN options? SSL and IPSEC options are available, and reading the Manual will be required to move to them, plus configuring each users machine, so should we spend time on this? or is this just FUD? (HowTos)
