WANTED: Quality Lost-wax Jewelry Vacuum Casting Equipment

Hello, I'm interested in finding a higher quality 3kg electric metal melting furnace with graphite crucibles, and a combo vacuum table for investing/casting. 120v power. Maybe a burnout oven depending on the size & other specs. There are a lot of cheaper machines made in China but I'm looking for ones that will hopefully last longer.. From Italy or the USA, etc.. Brands such as: Kerr, Vigor, Neycraft, Rio Grande, Gesswein, Kaya Cast, Paragon, etc, are of the most interest to me.. Please let me know if you have anything like this you'd like to sell, or any leads on used equipment. It would be much appreciated! Thanks for your time..
