My wife and I are thinking of buying a freeze dryer. Does anyone have any experience with this?

I think that it's a very expensive options for a pretty niche thing. Compare to something simpler like a standard freezer: A 15 cu ft freezer can be found for $200, and run annually for another $200-400 in electricity. 10 years of usage costs us around $3000 for a LOT of freezer capacity (assumes you cycle through things annually)
I think a freeze dryer produces a poorer quality product with quicker time to degrade quality even more. The initial startup costs are high (even if you build your own!) and maintenance costs are also high - probably exceeding $3000 for 10 years.
Unless you are bursting out of 15 cu ft freezer or you really need an off grid or backpacking solution, the light weight of the food is no benefit.

I think the quality of freeze drying is much better than heat dehydrating, but not a big benefit overall without investing in nitrogen purge packaging and such.

Unless a freezer and root cellar just can't work for you, I would avoid the cost and complexity of freeze drying.

If you can make a home business with it, Maybe. Just for home preservation, probably not. There are very few things that you can't do another method just as well.
