3270 Screen Scrapers

Looking through 2 screen scraping frameworks and thought I'd ask here for any experience. I need to 开发者_JAVA技巧recommend a framework for screen scraping an old 7032 IBM mainframe system and I'm currently looking at Inventu's Flynet (impressive, but expensive) and Zephyr's Passport HOI (cheaper and less feature rich). The goal is to encapsulate the terminal app in a webservice (WCF) and let less than 50 concurrent user access the service. Any ideas or recommendations?

Thanks

If I remember well the Expect tool can be useful. Other resources are:
