I've got a pair of budget DAP's for sale or trade.
I thought the X3 may be the incumbent for my tried and tested Sansa Fuze but alas it isn't - my loss is your gain as it can be had even cheaper than a fuze on the used market nowadays... The Plenue D on the other hand is a much improved player than the X3 but i just prefer thinner form factor players (which isn't very audiophile on my part )
The bad: The X3 has a lot of scratches on the screen, but you don't have a player like for this the screen, it's a old school oled ... The Plenue D has a small scratch on the back and the metal top trim piece wiggles a tiny bit. Neither effect performance and I don't suspect it to even be a problem in the future - this thing is still built like a tank.
