I'd love to have one, but not at the same price that I could get a smaller-sized floor loom! That only makes sense if, like the street vendor in Galway, you are going to make a business out of it.
I'll look at the newer "printed" ones, which may not be viable now but could be in the future. Also, at the prices I'm seeing if you see a used one, it might be worth picking up and paying to have it restored.
The "knitting frames" from Lidle or Aldi can be fun, they are like giant spool knitting, and are especially helpful for older people or those with issues in their hands that make holding needles difficult. I saw a video of a 100-plus-year-old man that makes hats for the homeless, the nursing home was able to keep him going with a "hat frame" and volunteers finish off the tops of the hats (sewing them closed).
For now, I prefer knitting on needles though I have some frames as backup, I haven't really used anything like that since I was a child - but I may pick up some of the larger sizes if I see them on sale.
