Welcome to the wonderfull world of Ducati
. . You can find some very good air cooled 750ss's for that price, and IMHO they are an excellent bike, good looking, wonderfull sounds, and the Ducati appeal that get's in your blood.
As for a monster, all of the above applies. it just depends if you want a fairing or not.
The best advice i can give is to try them for size, and get a test ride if possible,(not easy if it's your first bike).
Best of luck, (whatever you do don't compare them to jap bikes, i'ts all about character and smiles per miles)
