Do bear in mind though that under club rules you will have to do a separate flying competence test to be able to fly it on your own, anything over 7kg or turbine powered requires this. Having seen you fly your F14, I don't think you should have an issue with this though.
I bought my Boomerang intro as a complete package for £900 about 6 years ago - I have put in several hundred flights on it and it is still fun and has cost me £40 for a new kerostart plug and 3 or 4 turbine battery packs (around £25 each). They are out there, but you need to jump on your bike when you see one - same with excalliburs.
