Best workaround for Non-FrontPage hosts?

We use Frontpage for creating the basic structure of our clients' websites, and then tweak them with straight html. However, some of our clients have hosting plans already set up that don't support FrontPage server extensions. Then, of course, some of the components don't work when uploaded with ftp - such as hit counters, some text effects, and forms.

We've learned to work around most of these issues for the few clients that need it. My question is: Is there a good third-party source for e-mail forms that can be used in place of the FrontPage forms for these clients? We've tried some of the services like Bravenet, Freetools, etc., but haven't found anything decent.
