There's loads of second hand txpdrs for sale in the US, from $400 and up for a mode C. I saw a KT76A pre-owned with fresh FAA Form 8130-3 and 90 day warranty for $490 with new antenna ($400 without the antenna). Runs on 14v, it was $70 for a 28v kit.
Got to be worth getting one over there for £225!
