Last January spent £400,000 on England U21 GK from Norwich- Joe Lewis
Summer 2008 - 2 players from Wycombe was the sum of their summer spending around £200,000.
This January made one signing - around £350,000 on Congo Int from Fulham - Gabriel Zakuani
Other than the 3 forwards already mentioned (Boyd, McLean, MacKail-Smith) that's pretty much it.
Spent the odd £50-100,000 on non-league players, like Paul Coutts from Highland League - now a Scotland U21.
Transfer Policy firmly routed in the kowledge of everyones favorite "character" in football - director of football Barry Fry, using his non-league contacts.
As for Man Utd in 2.5 years Ferguson Jnr has made one signing a youth teamer on a one month loan (James Chester) so he certainly hasn't used his father to get up the ladder.
