All the computerized ones are pretty bad except this one: elmundo.es/traductor. It still is not perfect, but I do use it for no more than a phrase at a time. i recommend you to look on some Spanish education sites.... I saw one just two days ago about a conference in Spain on Special Ed and Autism. I'll try to find the link and pass it on to you. If you don't hear from me in a few days, just contact me personally.
