How much should I expect to pay for a high-frequency interrogator?
It depends on whether you wish to purchase a fixed reader, a handheld reader, a USB reader or a reader module. I have seen USB readers priced at less than $100, while reader modules often go for $100 to $300, depending on their features. Fixed readers and handhelds are more expensive. SkyRFID offers all of these options, but you can also purchase them from Amazon.com or Alibaba.
