Not for me, too few comics for too much money. I actually stated them but gave up after a few volumes. The pace really hurt, too.

DC are launching 90's nostalgia compendiums in the next 6 months (Lobo, Tim's Robin, Nightwing, Kyle GL) and I honestly hope they sell ridiculously well so DC focus on bulking issues in relatively cheap paperbacks. I love the Marvel Epic Collections for this reason (and the compendiums are bigger!).

As it stands, so much of DC will go uncollected but if they start really taking off and DC can do all of, say, L.E.G.I.O.N. in 2 compendiums at £40 a go, then they'll be on my shelf faster than you can say "hey, that guy's got the complete L.E.G.I.O.N. on his shelf!"
