Rewards...

[Janne Kemppi <jkemppi@xxxxxxxxxxxx>]

My ME campaign has moved forwards through several adventures now
and thus it has become apparent that characters have acquired
rewards from their work.

In my campaign I use system , where BE works as a investigation
company doing all kinds of work (car insurance claims are popular)
and this money provides enough bread to ensure all characters can
enjoy modest life style. However, successful missions reap them
extra bonus money that goes to their bank account. 

At this moment characters would probably want to spend their
hard earned booty from illegal actions to boats, cars, houses,
apparel, clothing, high life standards and like. 

How have you dealt with the question of rewards and lifestyle?
What kind of rewards characters get from theuir work? What
scale?
