If at all possible, buy the three beginner boxes. You'll then have three decent adventures (each with a substantial free downloadable continuation), maps, loads of cardboard character tokens to represent troopers, vehicles etc but more importantly three sets of dice, which while not essential is very very useful. You'll then have a wealth of material to choose from, and determine which 'flavour' suits you best without splashing out for the relatively expensive CRBs.
More dice are always useful, and this is by far the most economical way of getting more with other 'stuff' as well.
I remember when the dice were in-between printings, and another beginner box was the only way you could get more. And thus I have all 4.
