Also post on Old Style Money Saving board as they will give you loads of tips

whack the oven up high gas mark 8
rub the joint with veg oil and a little salt to get crackling
do at the high temp for half an hour (half hour sizzle)
then turn oven down to gas 5 and do for 35 mins per pound
take out for half hour before serving to ease carving
if you need to crisp the crackling up cut it off and put it back in the tin in the oven and whack the heat up again
make your own apple sauce and that will impress too

if you have hugh fearnley whittingstalls meat book that is good;)
best of luck;)
