        "I'd like to get on 222 and 902MHz for contest. I don't seem to be  
able to find radios. Are transverters the only  option now-a-days?  
What are good sources of radio gear for these bands?"
As your research has shown, there aren't any new all mode radios made  
for these bands. This is largely due to 222 MHz being a region 1 band  
allocation only.
If you want new gear, transverters are the only way to go. I have an  
Elecraft XV-222, which is a good performer. But it drifts noticeably  
from a cold start and gets hot at full power and high duty cycle, like  
a contest. The Elecraft is a kit. I use it with an HTX-100 IF  rig,  
but it really comes into its own with the K2 as an IF. I find the 222  
MHz performace with the Elecraft to be slightly better than my 144 MHz  
setup. Elecraft does not make a 902 transverter.
Downeast Microwave makes a nice transverter for 222 MHz and 902 MHz,  
which you can get either as a kit or fully assembled. It too is a nice  
performer, but I have not used one. DEM has a long wait list for fully  
assembled gear though.
You can also get new transverters from SSB Electronics and Kuehne  
Electronics, but they are quite a bit more expensive than the DEM and  
Elecraft.
Used 222 MHz gear is a good way to go, but it is scarce. Look at  
QTH.com. You will find perhaps a half dozen 222 MHz transverters  
offered for sale over the course of a year.
The Yaesu 736R had a 222 MHz module available, but it is expensive  
when found. The Icom 375, an all mode 222 MHz rig, is a collector's  
item and they are very expensive when offered for sale.
Sinclair Labs, Sinclab, offered a 222 MHz transverter in the 90s and  
those are occasionally found used.
This topic recurs from time to time on the list. You can search the
