Sheesh,

that's pretty expensive, even for the basic service. The library is the first place I'd hit if it were me, but I'm a cheapskate and my resume hasn't changed much from when I last did a revamp in 2000.
Honestly, the main turnoffs on resumes for me are grammar and spelling errors. I can overlook the text not being in the third person but sloppiness in the little details is pretty much a deal breaker. For $43 to $64.50 per page, depending on whether you have a three- or two-page resume, I'd almost have to expect that rewrite to be eligible for a Pulitzer Prize. Besides, I don't really look at form that much when I'm reviewing resumes. Substance is way more important to me.
Anyway, a resume should be targeted towards the specifics of the job ad so you'll still have to edit it before you send it out. I just can't imagine what Monster can do that's worth that much money.
On the other hand, I've never tried their service and my preferences and focus may not be the same as those of HR folks who usually do the preliminary screening of resumes, so take what I said with a grain of salt.
