To the person that asked about the IDW TMNT series, I'd suggest waiting until the hardcover collection drops in October with the first 12 issues of the main series and the first five micro-series issues (Leo, Raph, Donnie, Mike, and Splinter). It's a much better deal than the four-issue trades IDW drops for the series since there's eight for the main series (soon to be nine), four for the micros, Secret History of the Foot Clan, and Utrom Empire right now. Don't know how often those hardcover editions are gonna be released, though.
Rummaged through some boxes last year and found out I still have my VHS copies of the first three movies. The cases are beat to hell and back, but I like to think that just goes to show how many times I watched them and how much I loved them (still do, but now on DVD!).
