At $150,000 USD, REX is by no means inexpensive, but it does offer wheelchair users a practical and (almost) readily available means of getting out of their chairs. Other technology like HULC (which isn't intended for paraplegics anyhow, but rather to enhance strength and performance) are still in testing and could be for awhile. REX will go on sale in Auckland later this year and should be available worldwide by mid-2011.
