Iv got my motorbike learners now and i need a bike. dont know what to choose really, looking for one that isnt?

a gutless wonder and does have a bit of power. need one that is comfortable to ride on and doesn't brake my budget which is around 2 - 3 and half grand. not sure if that is an accurate figure think it maybe be to low for a bike that has all these quality's but just thought id say around there. im probably going to upgrade after i have finished on my l's. need one that turns good and is good for my body shape. don't care if its a Cruiser or a sports bike im up for anything. im nearly 6,3 and i weigh around 70 kgs broad shoulders and lanky. looking towards a 250 because iv heard they are bigger and a bit more comfortable for the taller blokes but yeah if u can find one that isn't a 250 and has all theses quality's im all ears. any feedback would be really appreciated =].
