And I agree, the license fee isn't bad at all, its just the initial license, renewals to member area are also quite reasonable.
As for legacy products, support for UBB.C has died, I don't recall if a EOL has been announced for support of UBB.C6.x however. But you can also always find support for all of the UBB products both here and ubbdev (ether of which you'll have me, your friendly neighborhood spamaholic to keep you company hehe)...
