Hey guys, I am getting ready to order a Cruz Reader, however I noticed there are different model numbers... for example TigerDirect and Amazon have the R101, while Best buy has the R103. Are these all the same, and just use different model numbers depending on where they are sold, or are they revision models (R101 being the oldest, R103 being the newest?)
Any help is appreciated! I'm literally pulling my hair out!

I just don't want to buy an older revision when I could have the newer one!
