A quick survey of Mission and Prairie-styled settles:

• Southern Joinery sells this model, pictured in tan fabric upholstery and walnut, for $2,850. They also have a nice range of spindle-sided tables and some interesting seating (check out the wide bench!) and case goods as well;
• The Arts & Crafts Home carries a range of pieces, including a very comfortable-looking paneled settle, and several others, some slatted and some with spindles;
• Ben Barclay Woodworking has an extremely attractive settle (scroll down to see it) that comes with any of several upholstery options for $2457 - $5043, depending on which you choose;
• J. Austin Antiques in Amherst MA has this slat-backed settle - almost Shaker in its simplicity - for $575; it looks like a shortened version of the popular Limbert design;
• you'd expect Warren Hile to make a beautiful settle; as with his other work, his is made from beautifully grained tank staves - white oak salvaged from wine casks - and looks sturdy as heck, for $8800 or $9800 depending on upholstery - Craftsman Home has a better picture of it here;
• Swartzendruber Hardwood makes a very Frank Lloyd Wrightesque settle, with vertical and horizontal lines reminiscent of the Robie House, and it can be made with shelf arms and back - Oak Park Home & Hardware carries it, although no price is given;
• One of my favorite furniture dealers, Rockridge Antiques / Rockridge Furniture in Oakland CA, carries a contemporary shelf-arm spindle-back settle for $3250;
• El Dorado Woodworks has a terrific sectional settle ($14,192), as well as more orthodox varieties;
• William Laberge has very nice settles and sofas (scroll down to see all of them), some paneled and some with spindle backs and arms;
• horror of horrors! fifty years ago, the original owner of this Stickley / Quaint Furniture settle painted it a hideous pinkish red. It's big and in good shape, otherwise - although not a deal at $1895, given the amount of work it will take to strip and refinish;
• Phil Taylor Antiques, in Ottumwa IA, has this paneled settle for $2450;
• Richard Bissell made this high-grain slat-armed quartersawn oak settle for a client;
• Randy of the eponymous Hardwood Floors by Randy built this attractive slat-back and -arm settle [ 1 / 2] with a nice wide rail all around;
• Michael Wollowski built this beautiful spindle-arm and -back settle in 2002;
• here are a few nice pictures of a slat-backed Limbert settle that recently sold;
• Maren Dunn Antiques recently sold this simple slat-backed short settle, in oak and leather;
• and of course, last but very definitely not least, we have one of Gustav's original settle designs, which was made of fumed oak; Stickley still makes a settle, not nothing like the original.
