A person can't really go cheap with Oxy/Acetylene. Acetylene is some touchy stuff. I've used Smith, Victor, and Harris and all are usable and regulators from one brand will work fine for others. I'd be scared to use some of the off shore stuff for O/A. All it takes is a bad o-ring to get in trouble. At least those three companies generally try to keep their equipment safe even if it's manufactured off shore.

A person can silver solder with methylacetylene propadiene gas (MAPP) but that's about as hot as it gets. MAPP is more stable than straight acetylene so it won't blow up on you unless you try to make it do that. I used it for making jewelry for a while but went back to O/A using a micro torch. Adding the oxygen in the mix is why O/A works so well. The others just use the ambient air to operate.
