I’ve bought one of these twice on Amazon with good results. Heavy metal. Shipped from China. Arrived 8n about a month. Note, though, that the holes are placed for screwing into a house. I wanted to hang mine from the lamp post, so I had to drill new holes at the top and attach it with wire. The metal is soft and drills with standard drill bits, though not quickly.

Winston.....my house did not have a number on the house or window.....soooooo...when I bought my house, the realtor gave me a coupon for a free sign to be attached to the light post. VERY important to have if you have a medical emergency.

Signs by JACKIE. GET METAL as it can be repainted by them for small fee if you ever move to another house. We had ours blown off when we forgot to take down during Hurricane. Good quality didn’t even scratch after being beaten. Look to see if realtor gave you coupon in your closing package as added bonus. Lot of deign shapes and personalized hinges to choose from (golf,, flags, palms, martini glasses, planes etc. ) Congrats on your new home.

Ace Hardware (outsources to one of the vendors at Market night) - easy to design in the store, reasonably priced and delivery in less than 2 weeks. Have used signs by Jackie also- they are a 12 week delivery time- much depends on the style you want as to who the best supplier is.

We also used Signs by Jackie. They installed it for a nominal fee. We’re very happy with how it looks.
