The Juki TL98QE and the Bernina 440 are both regular sewing machines and they have a longer throat. They are cheaper than the Pfaff Expressions 2.0, Pfaff Creative 4.0, and Janome Horizon, all of which also have the longer throat area.
The Elna 7100 and Janome 1600P-DBX seem to have a higher vs. longer throat area.
I'd keep an eye out on Craigslist and also Ebay. Ebay especially is a good way to track prices. Also, a lot of the times you can find these machines for sale by dealers throughout the US, often with free shipping.
