I think this place has about every tire tool available. Be aware that working with spoons can be a PITA and if they get away from you can hurt like hell when you get hit with one! Don't ask how I know that
Breaking the bead will be the hardest part, using a jack works well but you need be able to hook the jack to something.
I know what you mean about tire shops too, there is one within 60 miles of me and won't order in or install tires you bring in, shop policy crap, so I fixed that with this and now get all of my tires from Amazon or Ebay.

I was using a Harbor Freight manual machine, which for the money works well, but I'm getting too old for yanking on bars, so stepping on a pedal and having air do the work is a plus for me!
