Looks like Service and Rack grade Inlands are still available.

I would stay with Service as the price is not much more. One thing I know about CMP is that your premise is wrong - they do not sell the good ones first and crappy ones later. They have cases and cases of rifles that are pulled, graded and sold as orders come in. The last sold may be the best of the lot and the first could be a dog. Another thing about CMP is that they are very fair in their grading. You order a Service grade and that's what you will get.
More than a few of us bought a Inland when they first when on sale. Do a search - I think Steve posted pics of his. While mine says Service grade it looks damn brand new.
Anyway - send in your order !!!!
You can also post a Q? in their forum.
