Why would we come down on you for wanting a raise? More than anything else your goal should be maximizing the money you get in exchange for your time. You should be pulling for a raise at all times. But you should be working hard enough that you're indispensable so your boss would rather give you the raise than see you go elsewhere.
First off, never, ever, ever, EVER, EVER trust anything your employer says unless it's in writing. Don't make a decision until you know you're getting the better deal and not just lipservice. Second, next time your boss asks how much the other guy's offering tell him 3 dollars more, not 2.
You're in a very good position. You have a job so you can afford to pressure the commercial guys for more incentives. If they don't want to cough them up it's no skin off your back. You can also get away with pressuring your current boss a bit. Play them both and see which side is willing to offer more.
Under no circumstances should you feel compelled to be loyal to one or the other. Remember, your last boss hit some rocky times and he fired your ass on the spot. They don't give a damn about you. Don't give a damn about them. Just the money.
God, so atrocious in the Old Testament, so attractive in the New--the Jekyl and Hyde of sacred romance.
-Mark Twain
If people are good only because they fear punishment and hope for reward, then we are a sorry lot indeed.
-Albert Einstein
