I went through the same, and for reasonably priced set fidanza is what i chose. i paid 300 aussie deliverd. That is as cheap a set as i personally would go. They are pretty proven Or go some sexy big $ jap ones i guess.
Tha basic design i looked for was 5 or 6 adjustment bolts, spreads the load more so less chance of it slipping. If they do its a good chance you can kiss you valves and pistons bye bye so dont skimp. And also not too thin on the spokes near the center, seems wherer a few brands broke. like the early aem design. Apparently they fixed it with new designs.
Do some reading on dsmtuners and dsmtalk forums, good chance if it can break the yanks will do it. Take it all with a grain of salt though. Sift through the bullshit and idiot installations.
The real cheap ones i wouldnt touch likr obx ect on ebay, the coating comes off. heaps of sheap shit on ebay. Some have the annodising on teeth wear away also. or adjustin bolts snap. Likely due to over tourquing them however.Also read the tourque spech its stuff all. My instructions were in foot inches not foot pounds easy to stuff it up.
The aussie to american dollar is great so id look to buy from there.
Im not a pro engine builder just thats what i concluded after hours and hours of forum whoring.
