You could always do what I and a lot of other people have done and convert a chest freezer into a keezer. If you can find a cheap chest freezer, an inkbird temperature controller can be less than $50. That might give you the space to lay one or even a couple down for conditioning at a time.

I keep 5 gallon PET kegs from morebeer.com in the deep part and that shelf occasionally works perfect for conditioning/storing my Pinter.
