I have a KGUVD1P (2m/70cm), and I love it (aside from a couple quirks). I paid I think $120 for the radio, programming cable, spare battery, and a battery eliminator shipped direct from the distributor in China. Even if you buy from China, they do allow you to get service from their US support center. The reception is great, transmit is great (in 5W mode, 1W can be iffy), intermod is nearly non-existent. It's got pretty substantial feel (doesn't feel cheap), and the buttons/knobs have good positive 'click' to them. It also comes with a nice drop-in charger (which can charge your spare battery by itself) complete with AC and cigarette cords. For a sub $100 HT, you can't beat it.
Now it also has some quirks that bother me to some extent, but for me aren't dealbreakers by any means. You may feel different.
-It is not true 'dual receive', it is 'dual monitor'. It can only receive one 'side' at a time.
-The battery and signal strength meters are pretty useless. They're either full or empty, never in between. This could probably be fixed with a firmware flash.
-It's a bit wonky to program manually. DEFINITELY get the programming cable for your initial loading.
-A big part of the manual programming 'wonkiness' stems from the fact that it does NOT do automatic repeater offsets. You have to do it manually.
-The antenna connector is 'backwards' from what you'd expect. It's SMA, but the male side is on the antenna, not the radio. Keep this in mind if you want a different antenna or need an external antenna adapter.
-The headset jack is a Kenwood style 2 pin, but the speaker/mic jacks are backwards. The speaker jack is 2.5mm, meaning you can't just plug in a standard earbud for monitoring. You need to use an adapter.
-There is no external power jack on the radio. In order to use external power, you must use a 'battery eliminator' (basically a battery shell with a cigarette cord hanging out of it). This is probably my biggest gripe with the design of the radio. I'd much rather just plug in the cord than have to remove the battery and clip the eliminator on (especially since the battery latches are very tight and sometimes require fiddling to get both sides locked).
Some of these I knew when I bought it, others I found out. But even if I had known all of them, I would still have bought it.
And I too am excited about the mobile. If it comes out at $200 or $250, I'll definitely be getting one!
