janome's newest is the memory craft 11000 which they say has the largest throat on a machine in its category (as in not an "official" long-arm). i don't know what the price is, but it must be a doosey because none of the websites i've found so far for vendors state the price. just "call us". AND not all janome vendors list it on their sites. i'm guessing that adds up to around $7,000.
one of these days i'm going to make that call to get the price. not until i have the smelling salts on hand first, though.
