if you swap the fork over to a new frame that doesn't suck, then it's not a bad purchase.
will it turn your draft into a great bike? hell no. but that fork is a pretty good deal in and of itself.
is the fork 1" or 1 1/8"? something to consider when you eventually upgrade the frame, or not.
performance, as a company, generally looks down on that kind of 'advice' from what i hear. i think they're supposed to upsell through positive methods and generally shed the persona of a surly bike shop worker.
