People these days will just search their favorite engine for "LA Guide" which will happily take them to "
antonysguide.com" ... and a number of other websites on the topic that weren't (a) first in line to get the original domain or (b) rich enough to buy it on the resale market. In any case, unique names will be more identifiable than a generic term, especially for something like a guide that would be curated and reflect its authors. Examples abound, with craigslist, timeout and tomsguide being the ones that come to mine quickest.
Spend your money on desirable content (and maybe a little SEO) rather than a resale domain.
