We’ve been using Round Trip at the church where I’m an elder. It’s pretty great at preparing short-term teams for mission trips. But, for a while, we seemed to have lost it, once it became unavailable at the Christianity Today site. Now, suddenly, it’s available again here…

So glad. For $20 bucks, you won’t find a better cross-cultural training curriculum (complete with videos). (Probably couldn’t find anything any better than this at 10 times the price.)
For recommendations on all kinds of short-term mission (STM) resources including training resources, see the pdf list compiled by the Standards of Excellence in STM organization at http://www.soe.org/explore/resources/short-term-mission-resources. It includes Round Trip Mission (although the link needs updated). The resource categories include Bible Study, Culture, Follow-up, Organizing/Leading, Partnerships, Prayer, Support Raising, Training, etc.
