I've had good experience with Vanguard, Fidelity & Schwab, and we've done several rollover IRAs with Vanguard (from a Schwab 401k among other sources). I don't have direct experience with T Rowe Price but they seem to be well regarded.
To looking at expense ratios and whether or not you want face-to-face contact as REW mentions, I would always advise that you decide what you want to invest the money in as a significant factor in your decision before you do the rollover. Individual stocks, mutual funds (active, index/passive), ETFs, etc. Each of the firms have different strengths.
Just for example when my holdings were individual stocks and active stock funds I was with Fidelity. When I moved entirely to index funds, I moved all my holdings to Vanguard.
Best of luck, though it would be hard to go far wrong with any of the firms you're considering...
