Any home owners out there?

[TheRake]

Some of you younger guys out there may not appreciate this thread, but it might be good for future reference none the less.

I purchased my first home about 2 years ago and haven't really made any improvements since I moved in (I did have new carpet put in last year). I am now in a position, thanks to poker, that I have some expendable cash to spend on improvements. So really I have 2 questions.

1) What are the best improvements (aside from adding square footage) that I can make to increase the value of my home?

2) I am in the process of having 3 of my windows replaced. They are all standard size 3'x5' windows. I paid $1500 for the job (through Home Depot) for the windows and labor. Did I pay to much? They are nice windows, but not top of the line. they are single hung double pane(sp?) windows. I may decide to have the rest of the windows replaced and wonder if I should get some other estimates next time.
