If your looking at the Talisman hull from Metcalf Mouldings, it may be worth considering the Waverley hull Martin - It's very similar to the Talisman if you don't want a totally accurate model (most people probably couldn't tell the differences anyway!), and the big advantage is that the Waverley hull has the paddleboxes moulded in, so it saves a LOT of work!
It depends on just how accurate you want to be I suppose....
