Same card...different prices?

Hi everyone,

My company asks me for three different sources for the digital E1 cards. I thing the best option (is it?) is to get the Digium’s one 1TE121BF (I saw the equivalent ones from Rhino and Sangoma aswell). Anyway, I’ve been searching for resellers or something likely in order to be able to present this three budgets and I found a website that seems to offer the same card for less. The logic tells me that it is not possible but I don’t see any differences between the two further than the pictures. ¿Could anyone tell me if there is any difference?

From the Digium site: --> 1TE121BF

From e4 Technologies: … te121b.htm --> TE121B


It’s the same product.
