Is a comma required here or would an "and" or "-" make more sense?

I'm writing on a reward text for a Kickstarter crowdfunding campaign.
Is it correct to set a comma in the sentence below or would an and or - make more sense in that context?

You'll get your name listed on our website, if you like along with a link to your Twitter profile.

Answer

Some people resist them, but this seems to me a fine candidate for a parenthetical. You are offering a single reward that can vary slightly in nature based on the donor's preference. I think it's simple and clear to write:

You'll get your name (and a link to your Twitter profile, if you'd like) listed on our website.

This could be made even clearer if you ditch the slightly awkward "you'll get your" construction:

We'll list your name (and a link to your Twitter profile, if you'd like) on our website.
