Ha! I was just going to recommend stretching the budget to Prism MEA-2 and MLA-2s. I love my tube stuff, but a high quality clean analog chain can take you very far.
Right, somewhat future proof gear makes sense. The vari-mu does an excellent job of giving a project a finished sound, and I see they are selling them with switched input gain controls now. With that I think I could live without the mastering version.
