All those links above (except for the Walmart one) are dead (listed as "no longer available"). I did manage to pick up a "Used - Like New" Ruizu X26 the other day. It was at one of the links above, but I must have bought the last one, because that link is now dead. This Ruizu is due to be delivered by UPS today. It was only $6.61, so I couldn't resist. We'll see what "Used - Like New" means in Amazon descriptions. I bought a Sansa Clip (and a Fuze also) that were refurbs several years ago (ten?) The control wheel on the Fuse died maybe two years ago, but the Clip is still hanging in there. I hope it never dies. But I bought this little Ruizu X26 for the day the Clip does die - it's inevitable.
p.s. - One of the links above that used to go to an AGPTEK G05 now jumps to the G15, a different model. I haven't seen any reports about this model specifically. I wish I would have bought the G05 back when it was available. Good reports on it several months ago (by the same folks replying to this thread). But I put off the purchase for a tad to long, and now it's no longer an option.
