A question for all of you using leadpages...

I just signed up yesterday for a trial and played a bit in their backend.
I kind of like the interface and convenience.

The question however is - if I decide to move to some other lead-page platform, there's no way I can 'take the page with me' right ?

My consideration is that if I spend time and effort perfecting the lead page and then perhaps decide to use another service - I'll lose everything.

Were you clear on which platform you will use beforehand or did you go through a lot of testing along the way ?
I know there are WP plugins (Instabuilder, WP Profit builder) with a one-time fee, which might deliver exactly the same results (?), for a much lower cost (long term).
