My favorite software vendor AIT surprised me pleasantly yesterday by announcing the alpha testing of their translation memory product AnyMem. Because of the early stage at which the product is now, you won't find much info on the site but you can download an evaluation copy.
This is a very simple CAT tool that can only be used with MS word documents. It is quite easy to handle if you've had experience with any other CAT tools. My personal impressions after testing it quickly yesterday is that the software is quick and doesn't have problems with exotic language pairs such as Bulgarian-Greek. The main advantage of this software is its price: a single user license is 10 times cheaper than most of the competing CAT programs.
