Building the Ergonomic Guitar website make themselves invaluable.
The one design that crops up time and time again is that based around the Klein guitar as designed by Steve Klein (no doubt using the Ovation Breadwinner as inspiraton). Kleins have long been out of production with existing examples changing hands for many thousands of dollars, so it's not surprising that the design has been appropriated by other builders.
The above pictured guitar, however, is currently listed on eBay for $199 Australian dollars, which is approx £132.40 GBP, and a little over $206 US dollars at the time of writing. The body design, although a bit "blocky" and under-sculpted is copied from the Klein, although unlike the Klein guitar it is not headless (note the cutaway area behind the bridge - that's where the headless tuners would be on a Klein). The bridge, pickups and controls are borrowed from the venerable Telecaster.
Now, at this kind of price I couldn't comment on the quality of the guitar, but suspect that seeing as it utilises readily available Telecaster components, that it could be upgraded very easily and may well appeal to those on a strict budget wanting to experiment with guitar ergonomics.
