it's been a year since I've needed an RD. I last had an RX65 (that I loved). Heard it's not that great anymore... so was looking at the Sti, the 9500i, and the v1, though when I had tried the v1 (3.854), I sent it back less than a week after having it cause of all the damn falsing and what seemed to be low forward detection on Ka. Well, I've been reading nothing but good things about the v1 lately (3.863) and decided to give it another try. Pulled out my discover card, went to v1's website, started filling out all my billing info. Came to payment method- discover card not accepted. $hit.
