What's an RPG Programmer worth these days?

I'm interested in knowing what an RPG programmer is worth these days.  When
I graduated from college in 2000 and got my first RPG programming job, I was
paid $35k/year.  I was very happy making $35k right after graduation.

Now, with over 4 years of experience and have been at another job for over 2
years, I'm still making $35k/year.  Am I being "hosed"?!?!  I think my
salary should be at least around $45k/year.

With over 4 years of experience programming in RPGIV, what do you think is
the minimum an RPGIV programmer should be making?

If you're a programmer with less than 5 years of experience and making more
than $35k/year, would you care to share your salary and state that you're
in?  Send to me off-list if you'd like.

After I get some responses, I'll decide if I need to start looking for
another job or ask for a raise.

Thanks,
