Fatquartershop.com has a beautiful one. My favorite is Homestead Hearth. Expensive but so lovely and well labeled. I get most of mine off ebay or garage/estate sales. That is the only reason I know the brands I mentioned.
Stitchin Heaven in Texas has a great selection and is a large well known company.
Local stores have their own BOM that might save you some money even if you have to use their shipping.
