I like the Penguins just fine, and have to confess to enjoying the look of their matte-blank ranks on a shelf when stood all together. I wish they were still priced at the same as a pack of cigarettes, but I guess Allen Lane couldn't have predicted the sorry state of our world. As far as alternatives go, the Oxford World's Classics imprint offers comparable breadth and (often) superior critical material. They're also willing to print interesting variants; one example of this may be found in their offering of both the widely-known 1831 single-volume edition and the original 1818 edition, which contains significant differences. Two other imprints for which to watch out: The Norton Critical Editions are distinctive in all their colourful, oversized splendour, but they offer some of the best value for money if you're seeking an edition of a classic work that also includes a host of useful supplemental documents, critical writings, timelines, and other things that may be of use to those seeking a wider context. This can admittedly get a bit ridiculous in its scope (though I wouldn't have it any other way; the Norton edition of Joseph Conrad's Heart of Darknessis around 500 pages long, for instance, with maybe a fifth of that being accounted for by the novella itself. Similarly to the above, the Broadview editions (put out by a Canadian company of the same name) tend to have extremely in-depth supplementary materials. They're also known for offering just as serious and useful editions of comparatively obscure works as they are for well-known classics.
