Is there any company out there peddling a cut-rate version of Wufoo? You know, something with a moderately worse user experience that will let me collect 10x as many entries for $10/month.
jotform.com is close to what you're looking for.. You get more entries but not 10x more. And their 'almost unlimited' version is only $50/month.<p>Note that they also license their engine for surprisingly cheap (IIRC $250), so you could run it on your own server if you really wanted to.
Last time I looked, all the forms-aaS cheap-o plan response caps were pretty low. I usually just end up going with Google Docs Forms - not as nice, but free and unlimited.
