I have a 15" Bailey on a Next Generation frame. Love it. Bailey's now have a sit down version w/a table. He has classroom models at a discount. Here is the link.
http://www.baileyssewingcenter.com/sppa1prmawis.html The description says it's a 13" Bailey. The table is available on all 3 sizes of Bailey's. The largest 17" Bailey w/table is $2998.
Another option.
