That seems like the beige version of the KeyTronic Designer-P2, which is available from Amazon for $35. This was the first iteration of the Das, before they decided to spring for mechanical switches. The Designer-P2 is a very good membrane keyboard: I use it at work, because it is less noisy than my blue Cherry board (SMK-88).
The audio feedback may not be quite as crisp as a true mechanical-switch keyboard, but it's definitely there. The best way I can describe the sound is that it's like the patter of dime-sized raindrops on a white plastic chair. It is not a super pretty sound, but it seems to travel less than clicks, hence its suitability for office work. Once I got used to it, I find I can type on it faster than on the SMK-88.
In terms of supporting hand health, this is a fantastic keyboard. It is not a cool-looking keyboard by any means, but seems fairly durable, belonging as it does to KeyTronic's Lifetime Series. It is a healthy, responsive, fast, non-fussy, inexpensive keyboard. The sound is a bit weird, that's all, for those coming from quieter membranes or from mechanical switches.
Note: It is a PS2 keyboard, so you need an adapter to connect it to a USB port.
