Champagne recommendations?

Me & my fiance get married in 2 weeks & we leave on our honey moon the very next day. We want to get a champagne bottle, but we don't know what to get because we've never drunk champagne before. I was looking for something under $50 as well. Thanks in advance! Also, we're in the idea that we want to "pop" the bottle, like they do in movies where the bottle pops and erupts lol.
