I think I am going to avoid the non-cannon lenses for the simple fact that the 28-105 that I paid $229 for in 1999 is worth $220 right now on ebay. Funny as I can buy it new for about $229 now. My only concern is with the -c lenses and will they hold their values once cheaper full frame dslrs hit the market.

Oooooo please bring camera toys when you come. Hopefully I will have a 30D to play with then!
