Torchlight II is probably the best PC game around for dungeon crawler fans right now and it's only £2.99.
Diablo III still a bit pricey? don't worry Torchlight II rocked our world on release, showing the big studios how dungeon crawlers should be. Jon gave the game full marks in his review, praising the deep but accessible hack n' slash combat, engaging visuals and a huge exploreable world. At £14.99 it was great, so £2.99 makes it essential.
