If you go with CPM, you'll get 50,000 guaranteed impressions of a button that is in a fairly good position (top right is above the fold). If you go with print, you'll get a circulation base of 32,000 which is already less and $10 more expensive. What body has audited those circulation figures? Have you asked the sales team what sort of pass-along rate that magazine gets? You must also consider whether it's a weekly/bi-weekly/monthly etc magazine. Did they guarantee you a right-hand page? Where in the magazine will it be placed? Personally, I believe you have to evaluate who you're trying to reach and who can be reached with each of the above platforms. Bear in mind that a quarter page ad isn't usually effective without amazing creative, and if they're placing the ad at the back-end with the classifieds etc, don't expect it to perform too well.
