New Front door

#1
We are looking at getting a new front door installed and I was wondering if anyone had any suggestions on where to look, besides the obvious Home Depot or Lowe's.

We did use Home Depot, and they did a great job, but beware. The door was $500, but the total came out to around $900 because of installation and mortar replacement. Yea, that was a shock, and we weren't happy about it, but we had already paid for the initial fee.
