Probably not the advice you're looking for, but looks like you have a blog also and am assuming that some/many of your subscribers also look at your blog. So, you may want to use your blog to spread the word about losing your page so that your subscribers know what's happening and you don't lose many of them.

In addition, while you should keep looking at ways to recover your FB page, but you may want to take this opportunity to create a more traditional forum of your own.

You may want to look at AVSForum.com, Home-Barista.com and others for ideas on how to structure very successful traditional review/forum sites and while it may be more effort initially as you'll have to build it yourself, in the long run it may be more fruitful for you.

Either ways, Good Luck!!
