probably looking at tyre warmers first and being the person that I am

So far Ive got my options down to
Emtek. Anyone have any experience with these? they are going for 345 currently in an ebay sale.
Tyrsox. Ive looked up mixed reviews about these and they have been about for a while . they are about 300 shipped from overseas
IRC. Still looking these up but seen them work very well
Sumomoto are about 250 odd shipped from overseas as well. Ive seen these work quite well as well.
and finally the kaneg ones that I have heard good things about as well.
