You'd be buying aftermarket quality parts rather than OEM quality parts.
Borg and Beck are owned by First Line, and I wouldn't normally choose First Line parts for any car I was working on....however I've recently been working on a car on a budget and have fitted quite a few Borg and Beck parts, filters, bushes, etc. and all the parts seem to be perfectly good. In fact I chose Borg and Beck parts for some later purchases because everything seemed nicely made and fitted well but was low cost.
