I've been using the excellent non-IS version for some time and it's brilliant except that it's non-IS.
I've not been getting the hand-held keepers I want so I bit the bullet and went into Jessops in Kingston this morning.
The young fellow gave me an unbeatable price and then we had a brief discussion of the merits of various lenses.
He was a (Canon) photographer and really knew his stuff. The High Street and especially Jessops seem to come in for a fair bit flak on forums but this a very positive experience for me.
I had to shift a 17-40L to compensate for this purchase and I shall be looking to off-load the 100 non-IS.
Off to Kew Gardens now to catch some creepy crawlies.
