Here is one pair that you can buy in the US for under $50.00 USD if you shop around on eBay. Due to modern materials that are very strong but not as heavy as the antique shears, have a ton of grunt and hold their edge well. there is a magic rule with shears, bigger is always better as long as you can pick them up (IE: Not too heavy). There is no such thing as a "Swiss Army Knife" for tailoring or general purpose clothing manufacturer, almost every tailor owns shears and trimmers of various sizes to perform different tasks. the only real trick is to keep them sharp.
