Doing bench press with slight incline

[ChgoSportsFan]

Rip,

I have an adjustable bench. The problem is that the (actually very sturdy) piece of shit doesn't go exactly flat.

I am willing to buy a flat bench, but before I do I wanted to ask you - if doing Starting Strength, do you think it's a problem to use the bench with a slight incline when doing bench press? What would you recommend to your trainees?

I attached a picture of the bench on the "flat" setting. I had to re-size it so I hope it shows up large enough to see.

Thanks for your input.
