I'm find this tiny tool to check PR and alexa. Put your url's int text file one per line
And load it into program with load file hit check and that's all. Gives you current url pagerank and alexa rank. Export result's to text fie if you wish.
There is no proxy support so your not probably able to check more that 1000 urls at once before Google calms you down after few hour's your able to check again.
