I'm in a similar boat. I recently had to replace my N1, and it will be sorely missed. Especially the LED trackball! Sadly enough, the google nexus is too big for my taste, and I didn't really want to spend $400 up front on a new phone so I picked up another phone instead.
I've vowed though, that as long as the next Nexus device is sized more like what I prefer, I will buy it!
I bought the japanese galaxy nexus for around $325usd, shipped to hong kong via yahoo auction jp a month ago.
Though I am still flashing different roms on my N1 to play with
