PSI as transit carrier

I've been approached by PSI who seem to be taking a rather aggressive approach at selling their transit service as an alternative to the 3 major players in Canada (Sprint Canada, UUNet and Teleglobe). Their pricing is very aggressive but I'm just a router nazi and care more about knowing what the service is like and wether or not PSI is as well connected as the aforementioned competitors. Should I spend the money and buy from them or just peer with them, and get all their local and customer routes at only the price of a local loop? Anyone out there use them? Comments?
