When you consider that Adam Drury cost just £500k back in 2001, it got me thinking about who we all think has been the clubs best 'value for money' signing. Probably best to stick to the most recent 15 years or so as values have of course rocketed! I suspect Holt will get a few nominations but I'll go for Drury. 
Any other thoughts?

I just know that at some stage today I am going to get a calculator out to try and work out the best value for money signing!
