I don't know what everyone likes about contact form 7! I installed and removed it several times.. just don't like it, no preview, too much coding.
Fast Secure Contact Form has alot of potential: They don't hound you to buy their "pro version" and only ask for a reasonable donation for support. Great preview and lots of settings. Seems totally customizable with no limitations I have found yet (unlike webdorado's form maker and others)!
>You cant delete the sample forms and fields, I like to start from scratch (you can change them somewhat tough).
>You can choose to display checkboxes "inline" but how the heck do you align them?! I have like 20 checkboxes and they display as a conglomerated mish mash, I would have like them to display like in columns or be able to center or align left or right EASILY without coding.
>The biggest issue is that I have literally tried everything and emails keep going to spam. I have tried like ten contact forms and although most of them have more cons than pros, they ALL send emails properly except this one. Too bad, I kinda liked this one.
