You've heard the story before

... I just purchased an old home with very old single pane, double-hung wooden windows that are in terrible shape. I am looking to purchase 39

vinyl new construction windows to self install.
Here are the big questions:
1) What is the best brand or brands of vinyl new construction windows?
2) Any ideas/recommendations on where to buy?
I live in Somerset County NJ and have looked at Lowes/Home Depot. I wasn't thrilled with what they offer. Obviously, I want to get a good deal but I also want a good quality window. There seem to be so many manufactures of windows it gets really confusing. I know Schuco is the brand of choice around here but they don't sell to DIY'ers.
Thanks in advance
