Want some difficult MIP models

I need to convince my boss to approve budget for a commercial MIP solver compared to a free one. I just started to do some modeling with GAMS so my models are still small. You have some bigger ones I can use to show some hopefully significant performance improvement?

Here are some simple but difficult to solve MIP models: http://www.amsterdamoptimization.com/benchmarkmodels.html.
