I saw this one as well but we have the same problem, budget. And for me (i am in ireland) this is requirement cause the roads are very, very bumpy! As well as this if you have to pay 371$ for this stuff, we have to pay 360EUR (around 450$). Crazy when you think they are made in Italy!!
And can't by them in the US cause have to pay the VAT and duty on it when it does arrive! So try to find a cheapy way out!
