What adjustable rockers to buy at a reasonable cost?

I would look for some good used Isky, Crane, Erson or Mopar ductile iron rockers. As for what you mean by "reasonable" I don't know, but you can usually get any of those three brands for around 300 give or take used, shafts and all. I was very fortunate that I have a close friend I hadn't seen in some time just drive up in the driveway one day late last year and GAVE me a pair of 906 heads, a 440 HP intake and a set of barely used Isky adjustable rockers simply because he was never going to use them. If I have any luck at all, I will.
