Regarding replica firearms...

I have started to look at replica firearms to add to my collection. Specifically firearms that are either extremely rare, expensive, or impractical to own a live variant. I found one website ReplicaWeaponry.com that offers many different options for modern day back to the colonial era. But cant find much info regarding if the site is legitimate. Has anyone ever purchased from them and could offer some advice? A few retailers such as Ebay and Optics Planet also have a few options but at a significant price increase. But I do have those backups as I know ill either get the item or my money back for sure.
