Any difference in quality?

Looking at some 5mm spacers to stop tyres rubbing on the back.
Wondered, is there much quality difference between getting your pants pulled down at about £54, or just getting some pearlers off eBay for about a tenner.
Such as http://cgi.ebay.co.uk/2x-5mm-Alloy-...841?pt=LH_DefaultDomain_3&hash=item35aeae1c89

Cheers.

£54 for a pair of 5mm spacers? where the hell do you shop!
