if you sell high end meshes that lots of people want to buy

then you may make high end money,

 but if you sell high end meshes aimed at a small specific

market and hope to make large volumes of sales

then I think it's less likely that you will make the

sort of money you may aspire to. Just my take on it,

not definitive by any stretch but working on simple

economics of supply and demand........But it depends

 on what your expectations and desires are.....

.I always think of that old adage, ,

"Give a man a fish and you will feed him for a day,

 teach a man to fish and you'll never sell him another fish"  LOL
