Depends on the type of looms and the brand. My knitting board and afghan looms were all in the $20+ range, but you can get a basic, plastic set of 4-5 round or rectangle looms in the $10-15 range usually.
So, while they're more expensive than they used to be (not surprising, everything is more expensive) the basics can be pretty affordable in the long run. Especially if you can find coupons.
