no one replaces their own belts?
Yep, but for my bike (a '99 M750) there are no non-OEM options available, so I just got to the local Ducati guy and say "belts for a '99 750 please".
There are, from recollection of past discussions, some "Bucci" brand alternatives, but I think they're only for 900s, and am pretty sure they won't fit your 800 given what you've quoted from the ca-cyceworks site there. Either way, Chris at ca-cycleworks is a great guy and knows what he sells, give him a call and he'll set you straight (and post back in this thread with the answers when you get them too please!)
cheers,
big
