I honestly did the referral link to the model search because prior to doing so I was trying to price check, but don't have a programmatic way of doing that without access to the Associates API.
I did it manually at first, but then saw price drifts within a couple of days. On top of that, some models on the list were out of production and I was hesitant to link pricing to models that were likely to be refurbished, old stock, or listed as used.
I wasn't aware of ASIN, I do like the approach better, so I can work on getting that switched over when I get free time over the weekend.
Thanks again for your feedback!
