the ET model never actually made it to these shores, I was led to believe. the few that are here were imported from elsewhere. that was the bike that got me back into BMX. I had one on order from Groove racing after talking to him at a Peterborough regional late 06. they never turned up as the distributors at the time were shit.
good luck. they do appear on the ebay every so often. there was a US site that was selling them, cant remember the name though. I found out about it as mike at dialled bikes has ordered stuff from them and was talking about the site to somebody else. I saw his post and had a look on the site and saw them. might be worth asking him.
