I was in the Sigma 30/1.4 camp too. But have fun with the 28/1.8.
And regarding to transfer to Full Frame; sell the 30/1.4 then buy a 50mm.  Because a 50mm will give you a similar shot on FF as the 28-35mm will on Crop.

Thank you everyone for your advice, I really appreciate it.  I think I'm going to go with the 28mm f/1.8 as it seems like the best compromise of being somewhat wide, maximum aperture, capable of being used on FF when (hopefully) I switch over, optical quality/ performance, and price.  Thank you again for all the replies, I looked at a lot of lenses I wouldn't have before and I'll keep in mind until I actually purchase the lens.

Have fun with the 28mm f/1.8!  I love it for landscape shots.  One thing it has over the 50mm f/1.4 (my most used lens) is a 7-bladed diaphragm, which makes great 14-point stars on bright lights at smaller apertures.  I don't know why lenses with an odd number of blades make "stars" with twice the number of points, but perhaps neuroanatomist can explain it to us... ;)

have you considered the EF 14mm 2.8 IS?  GREAT lens!!!!  The EF28 1.8 is really great but a used 28mm 2.8 is a really great lens and can be had for under $150.

28mm f/1.8 - useable on full frame.
sigma 30mm f/1.4 - wider aperture.

Take your pick.

Just a theory:
With even numbers rays overlay themselves in pairs, with odd number rays spreads does not stack, i.e. 7 blades create 14 "rays", 8 blades would create 16 rays, but due to "stacking" it would look like 8 rays anyway ;)

I'm with neuranatomist.  17-55/2.8 IS is the way to go.

I've gotten great shots inside museums with my 400D + T17-50/2.8.  A stabilized lens would give you an extra 3 stops.

Another option would be 15-85 IS.  Great travel lens.
