What this is, is an iRiver H340 US model. The firmware has been flashed to 1.29K and then flashed again with Rockbox bootloader. I installed the latest version of Rockbox H300 Experimental Build. I bought a brand new Newertech 2200mah battery for a 1st/2nd Gen iPod and reversed the wires for it to work with the iRiver. I also bought a BRAND NEW (EXTREMELY HARD TO FIND) Toshiba MK8007GAH 1.8" 80gb hdd and installed it. So this is about as good as it gets.
I have 58gb of FLACs loaded on the hdd right now as well as 2gb of mp3s. It also has (for S&G's) EVERY official Doom wad on there to play Doom inside Rockbox. I can play FLACs for 18+ hours with this new battery.
I have over $500US in this DAP now with all the mods, plus alot of time. I will let it go for $375US covering shipping and paypal.
