Well good luck with the decision making. Tyne Models are semi kits yes but they seem quality although sometimes it can work out a bit more pricey. Model SLipway include everything and the plans and instructions leave very little to be desired. There is always Mountlfeet as well, they have a few nice tugs too.
Marks Model Boats also have a new tug semi kit out which is a very competitive price at £175. The price at £175 includes motors and couplings and Korts. All that is otherwise needed is a few sheets of ply or plastic card so its more complete that some full kits.
there is also a build link on Model Boat Mayhem
