i refer you to my post the other day... I am not going through all that again

to reiterate one point though.. if you buy your products wisely then you will make cost savings and improvements on your products by not buying your cleaning kit from a [large multinational auto general equipment reseller]
think of it like this...
if you were into ICE in a big way and wanted the best soundz possible... would you get an install/equipment from a [large multinational auto general equipment reseller]?
if you were into cycling in a big way and wanted to do competitive races... would you buy your bike and equipment from a [large multinational auto general equipment reseller]?
if you were into camping in a big way and wanted to make sure your tent was useable on more than two occasions... would you buy your tent and equipment from a [large multinational auto general equipment reseller]?
if you were into rimz in a big way and wanted alloys that didn't warp on their first outing to the B&Q carp park... would you buy them from a [large multinational auto general equipment reseller]?
the [large multinational auto general equipment reseller] caters for bob smith and his ford mondeo... barry his son and his citroen saxo and countless other middle of the road punters...
in short... if you want decent product then go to a specialist reseller... make the effort to find the good product, both in terms of performance and vfm and you will be rewarded
