iirc I paid £20 for 512mb ddr400 in 2001, not exactly cheap though memory capacity was lower than todays standards so its hard to tell if that was cheap or not, an other thing is around that time hdd's were around £1 per Gb!!! compare that to a 1tb hdd that can be found for £60 today and thats 16p per Gb, though ram prices are crazy high atm
