Came across this site while searching for a spring compressor to buy. Makes it look soooo easy.

As to buying a Mercedes spring compressor, I don't want to spend $800-$900 for Klann so the $200 ones on Ebay look tempting. Made in Taiwan by JTC Auto Tools http://eng.jtc.com.tw/products/products_list.php?offset=1&cid=183&search=nvl() has anyone bought direct from them? Anyone have one they want to sell?
