We began using the rotation model in March 2006. We decided to use PowerXpress began we didn't want to write our own material. Also, a big positive in selling this new idea to the congregation was that we were using United Methodist approved curriculum. There are many positives to the material but we have some frustrations. The biggest ones are in the computer and movie areas. The lessons are written using software and videos no longer available. Then we have to scramble for something else and still write our own lesson. After purchasing 6 sets of software that cost $90 each, then I discover that new units require new software! Also, I searched and searched and finally found a set of the video series on eBay that was recommended. Now I find it isn't used very often. The curriculum people at Cokesbury are very helpful and will tell you which of the older units are in the process of being rewritten and lots of other good info. So if you go with PowerXpress, make sure you call Cokesbury and talk them before planning your scope and sequence. It'll save you a lot of headaches. Overall, I would give this material a thumbs up simply because we didn't want to spend a lot of time writing or adapting other material.
