hey, I'm trying to make a diagram for a site I'm making, but using paint (or, at least, how I am using paint) looks rather ugly.

something that should look about like this:

for some reason, I can't add text (damn MS paint), but it should have "banner quality" next to the arrow, beneath the left column "without Pure Fight Technology" and beneath the right column "with pure fight Technology".
And yea, they are supposed to be at about the same hight, showing the criticism or something like that, though the hights can vary a little.

Now, it looks terrible. If someone could please help and make something cool, I'd really appreciate it.

Also, I'm hoping this will be easily compressible as PNG, that is, use a small number of colors and have crisp, sharp edges.
