Hi Barry, welcome to the forum
The choices really are endless, before shopping around try to decide what model varient you want, WRX, STi, Classic or Newage, import or UK Spec and so on.
There is a lad on here called Dan (ScoobyWhore) who just bought an MY05 (I think) UK spec STi through the car shop, he says the service was top and could not pick a fault with anything they did. Dont think they would do an import though. I suspect they would take your Type R in part ex without any probs, source the Scoob for you, bring it onto the island, put it through a Manx test if neccessary and then register it here saving you a whole load of time and hastle
Welcome once again mate, anythiung else you know where to find us
