1 GB or 2 GB Clip for audiobooks and podcasts?

RE: the model numbers – I found this thread: http://www.head-fi.org/forums/f15/beware-version-1-sansa-clips-showing-up-version-2-packaging-380971/ .  One poster says that “the v1 skips with large lossless files such as WAV” and that there may be background noises.

I am wondering what I should do – I just picked up my 4GB Clip from Sears, and I am sure it’s a v1, tho I haven’t opened it yet.  And when I brought it home, my kid got interested in it, so I went online to Sears, and they no longer had the 4GB model at the price I got it for ($37 with tax), but they did have the 2GB Clip for $29, so I bought that.  I figured I would grab it, and return it unopened if I hear too many bad things about it.

So – did I get good deals or should I return these items?  If it matters, we aren’t audiophiles, and I will probably use mine more for voice than music.  Thanks!
