I have a Wouxun KG-UVD1P here and for $105 it is a great value. It's a dual band, they have 2m/440 and 2m/220 as options. it is not a true dual VFO like the VX7R though, more of a dual watch A/B where you can monitor two fixed frequencies, or scan on one and monitor a single on the other.
Has some quirks as mentioned, female SMA connector, but you can simply buy antennas for it or an adapter if needed. I have one to BNC that I use now.
The performance of the Wouxun has been perfect, no issues, works great. Much better on high power use for rag chew than my VX7R can do by a mile, it barely gets warm.
For $105 it comes with
radio
battery
stand up charger
car charger
headset/mic (this is junk)
programming software is free
I added for $18
1700mAh battery
$9
Programming cable
$22
speaker mic, that has louder/better audio than any of my other ham speaker mics, built more solidly too
A Motorola it is not, but it is a nice piece otherwise, totally a good value for the money.
I don't know much about the Quanxeng radios, the Puxing radios have a similar rep to the Wouxun from local feedback. There are probably a good 50 Wouxuns in use on my local 440 link system and no problems aside from user error so far over the year they've been around.
