Hey Rob:
I got the pair of PX-777 you sent while I was home on leave. They look great but I did not get time to fire them up. You know anything
about the KG-UVD1P TX/RX 136-174 216-280 someone is selling on eBay? It sounds like a great combo but might not be FCC type excepted like your gear.
There are very, very few Asian radios that are FCC certified unfortunately (the KG-UVD1P isn't). It costs in the neighborhood of $10,000 to obtain the certification. The certification is supposed to assure that the radio operates under certain parameters, such as spectral purity, so that it doesn't transmit dirty signals across the band and cause interference.
Right now those Asian manufacturers don't see a huge benefit in obtaining certification because they are able to take advantage of eBay and similar sites to sell their goods worldwide. Not every country regulates its telecommunications rigidly and many countries are more lax in their enforcement than the US.
Now while you can legally use a non-certified radio operating properly (cleanly) on amateur radio in the US, its importation is not legal (and could, but rarely happens, be confiscated at Customs). So the ownership of a non-certified radio operating on amateur frequencies is OK if you are able to obtain one.
The problem that arises is this... As an amateur you are still required to meet certain transmitter specifications. If the radio you purchased is causing out of band interference you have just raised your profile with the authorities. For example, the 2 meter amateur band is sandwiched in between two military bands. Above that you have numerous public safety agencies (police, fire, EMS, etc.) operating there. If you are using a "dirty" transmitter you could very conceivably cause interference to those services.
As you would expect, you would more likely be looked upon by the FCC with more sympathy (READ: small or no fines, just cease operations) if you have a certified radio than if you had one that wasn't.
So, it is up to the individual to determine whether it is worth using a non-certified radio or not. But I do think that it is just a matter of time before you will see more certified radios on the US market.
