I use instapage.com. They are the least expensive out of the landing page builder solutions with a/b testing out there.

Wix is a way cheaper option.

The cheapest option is probably wordpress. You can buy landing page theme for wordpress on themeforest.net.

Good luck.

Instapage is excellent. Fast, reliable, high quality, easy to cancel when you move on.

It's worth the extra few bucks for the time you'll save.
