I have been using, and am pleased with, a pair of these-- only the "121" version, not this new style 125 version, for a year now, as a "house" battery bank.
http://www.wegosolar.com/products.php?product=SKR%252d125AGM-Stark-AGM-12V-Solar-Battery-Sealed-125ALast year we had discussions showing that these were the same battery (according to their specs) as the 121s that UPG in Texas was selling.
The Starks come in a box that says, "Made in China" if that matters
I see now that Randy at bestconverters is selling these:

I can recommend these as house batteries for sure. I don't know how well they would do as starting batts if used in a dual role. ( I have been thinking about that based on LY's posts)
