Gabh + Time = ?

I've decided that if I'm ever to achieve anything, e.g. finish my book, end poverty in the world, travel to other worlds, you know, the usual wish list of those exposed to science fiction and Stan Lee at a tragically young age, I need to step outside time; so I'm in the market for a Tardis. Not fussy about model, but I would like one with a chameleon function; I plan to disguise it as a comic/old game shop and roam the cities of the universe... Any offers?
