I have the June 2006 issue of "Professional Pilot" right next to me and it happens to have the annual corporate pilot pay study.
B-200 Captains are listed with an average salary of $57k with a lowof $41k and high of $69k respectively. For a "corporate" position (I imagine this is a part 91 department)
On the Charter side, FO pay ranges from $28k on the low to $47k being high and an average of $33k per year. Captains are making anywhere from $39k to $62k with an average of $51k.
These are all higher than the same seats in a Lear 24 or citation 500.
