Look through this list here. Lots of options and price ranges just go USA made if you would. Personally, I would go vintage. They are lighter weight and made very well. There are many ways to get them. If you go with most restorers that specialize in buying and selling, they will most likely go high. I am not that way. If I get it cheap and restore, I pass it on with just a small mark up for my time. I enjoy bringing them back to service. I have done hundreds of pieces. Ate up with it. Dealt with several here on OAF. Also, if you are into it find used vintage and restore yourself. There are bargains still out there as mentioned by @snagged in outlet 3 at resale stores, garage sales, estate sales etc. I have actually found some dirt cheap and gave more than asking price. Do your research and if you need any help just Message me.
