Hey guys. I know nothing about chronos. Never owned one. I would like to have one for load development. I see a ton on ebay in the $80 range. Would this be sufficient? I am sure that like anything else I could probably spend whatever I want on it, but I just want a basic unit. No need for a printer. I can write it down and therefore one less thing to break. Also, what is the difference between all this alpha and beta stuff that I see? Thanks in advance for the advice.
