Since you are from the UK have you looked at the Chris Foss range of kits? Just Google Chris Foss to get their site.
Never flown one myself (they don't seem to find their way down here) but they seem to have a very good reputation. A WOT 4 or maybe an Acro Wot might be just what you are looking for.
No doubt one of your fellow Poms might be able to expand further!
