Mxpx and relient k but I'm guessing you heard of them.

There's also slick shoes, ace troubleshooter.

Check out tooth and nails records. I don't know what their lineup is now but they used to have a lot of those types of band.
I just want to know that I did all I could with what I was given.

You can check out Icon for Hire, but they are more like Rock-Punk with a lot of pop influences. They got some rock-punk and punk-pop songs.
Also they aren't  categorized  as christian band. However, they said in an interview that the christian ideals are their driving forces.
And they are in Tooth&Nail records, which mr.retard has already mentioned.
