Bob, the Artglass prices are similar to the TruVue prices where the product features are the same. For instance, Artglass AR/UV will be similar price to Museum glass, however, Artglass AR without UV will be less expensive. One of the problems that we have is there is not a lot of sizes being brought into the US at this time so we have to charge for cutting and scrap for just about all our sizes except 16x20. That is why our 16x20 price will be so much lower than our other sizes, and much lower than even 16x21. Although the price is similar, I feel Artglass quality is higher. Museum glass has an orange peel effect that can be seen if you look closely at certain angle and I have run into issues with black specs. I have not encountered either issue with the Artglass. However, if you are really concerned with UV filtier then Museum glass is better. UV filters have other issues in that they do not really provide full protection and they can cause color shift issues with papers that have optical brighteners.
