Ellison & Reliabilt
Atrium manufactures the Reliabilt 8700 and sells it under the Ellison label - seems pretty standard for Atrium - I would say it's an okay vinyl window, nothing great but not the worst out there by any means.
I don't know much about this company but I check and they aren't rated by the AAMA or the NFRA - which means that Ellison can say they windows have any ratings they want (as opposed to being indepently tested and rated). My suggestion would be to contact local contractors who have worked with Ellison in the past and can give you a fair estimation of their products and customer service.
