"Replacement" brand auto parts. Are they any good?

Another site, which has the replacement unit for the front shock/strut, is at www.discountbodyparts.com. The price for the OE unit is $33.87 instead of the $84.00~ of the KYB listed at another on-line place like Autozone or O’Reilly, which sell their parts for about $85. Although I like the price, I have not heard of the manufacturer before; I’m all for low prices, but not when it comes to my families safety.
Have you come across this manufacturer before? “Replacement” is the name of the company.
Thanks
