Hey jdrootes--I put a couple links on a similar question of yours, but a lot of this depends on your budget/what kind of door you're looking for. Are you looking for something wooden/glass/steel?
Thanks!

Thanks Vanessa. I was looking for steel. Mid-range on price. Thanks!

No problem! I'd also try searching in our "Professionals" section. You can type in "exterior doors" in the top search bar, search under professionals, and narrow down by metro area/style. There's a ton of great product!

Thank you. That's a great suggestion. I'm new to Houzz! ;)

Hello, we offer lots of contemporary or modern doors in solid mahogany wood with glass or stainless steel aplied, you can view some of our contemporary doors on our website http://www.decodesigncenter.com/products/exterior-doors/contemporary-entry-doors/ by going thru the different pictures. Be careful with "steel" or wrought iron because usually steel will rust even though powder coated. If you want a metal, then use aluminum which is rust free less maintenance.
