I have to agree with bluskis here.
Whether or not you are allowed to do your initial training in a twin, I strongly suggest that you don't.
Apart from the inevitable extra expense, you will be trying to master an aircraft which is far more advanced and probably less forgiving than most singles. In the early stages of flying, you don't really want the added burden of a retractable undercarriage, constant speed propellers, the niceties of assymetric thrust and the fact that most things are going to happen before your brain has even caught up to where you already are.
Basic trainers have been built for a purpose. Notwithstanding that, if you don't like the idea of a Tomahawk or a 152, go for a Warrior or a 172.
When you are proficient in flying a single, then move onto a twin - it's a whole new exciting challenge.
