You could get full ilevel 251 tier set just from farming badges from queueble "heroic" dungeons and never stepping foot into ICC. There was a couple of ilevel 264 items on the vendor for badges (belt, chest, gloves, cloak, trinket, accessories like totems librams) as well and then your 2 piece ilevel 264 crafteds (boots and legs). Saronite wasn't THAT costy at least on my realm bar the first 2-3 weeks or so thanks to ICC being highly puggable from the get go.
So max ilevel was 277* which was heroic 25 man ICC, and you could get ilevel 251, you could get your tier set bonuses, your sockets, and a lot of ilevel 264 pieces.
Compare that to today. The gap, the quality of the items, everything.
