I've been looking for a budget friendly DD HU and was wanting to get opinions on these two units compared to each other

PLDN750D-$198.53+SHIPPING
PLDN750D - 7'' Double Din TFT Touch Screen DVD/MPEG4/MP3/DIVX/CD-R/USB/SD/AM/FM/RDS Pyleaudio.com ::: Your source for Car Audio, Mobile Video, Neon Lighting


AVIC-U310BT-$108.51
Pioneer USA - AVIC-U310BT - In-Dash Navigation Receiver with CD Playback, Built-in Bluetooth and 4.3" Touchscreen Display


I would like the good and the bad on these units
thanks
