Those look like they could very mechanical feeling. I could be wrong, but nothing beats the feel of a massage from another person. How about this? On your computer, print up a coupon booklet where your wife can tear out coupons where YOU offer her a "free foot massage", and other assorted acts of love (wink wink, nudge nudge). Attach the coupon booklet to a gift basket of massage lotions, foot creams, etc. My gf did this for me back when we were dirt poor undergrads (the coupon book, not the lotions and smelly creams). Put the rest of the money towards something else you think she might need. If you're still set on getting one though - get the one that offers the best value for the price. Ignore the looks. It's not something I'd want to keep out in the open for company to see anyway.
