been shopping for hard cases and i've narrowed it down to these three:

trico iron case
serfas SBC bike armor
serfas SBT

ive read quite a bit on the trico iron case and a little on the serfas SBC bike armor. between these two, i'm leaning towards the iron case because of the closing straps. they seem more durable in the long run over the latches of the bike armor, but would like to know if this is true with those of you that have actually used these cases. if they're equal in quality, i would actually go with the bike armor because i'm finding better prices on it.

i haven't found any reviews on the serfas SBT (http://www.serfas.com/product_details.asp?ID=818), but anyone have any experience with it? i'm particularly interested in this one because it's SLIGHTLY smaller than the other two (i have a 49cm frame and worried about shoving it into a car) and it uses the closing straps. it doesn't look like this has the internal straps like the bike armor does, but are they necessary? price looks to be about the same as the bike armor, possibly cheaper.

btw it's a steel frame if that makes a difference. thanks for any help!
