i am not a carbon fan. i prefer old school aluminium or if budget allows titanium, but if you want carbon there are for more interesting looking frames out there, cervelo, pinarello dogmas, cippollini frames some bianchis etc...for boardman read bland.
but if you are interested in a budget carbon frame, they are 'apparently' available somewhere on the net from china/taiwan sans paint for lots of $$$$ cheaper. not sure where as i prefer alu, but if you do a search you might get a nice frame and then a personal spray job.
only my opinion of course
