PRACTICAL SAILOR Magazine did a review once, check their web site. It was a combined review of the Montego 25 and the O'DAY 25, but might still give you the info you are looking for. Also, I believe there is a Montego Owners page on SAILBOATOWNERS.COM? Not sure how active, but worth checking as well.
Sorry, both leads are false alarms! PS did review the Montego, but the review is not on their web site (BTW, sorry Randy that I didn't see your link to PS in the header of this page!) And Sailboatowners.com doesn't appear to have a Montego group, maybe YAHOO Groups does? I have the PS review, but it is copyrighted ,can't be posted online. It is in the book that PS published called "Practical Boat Buying".
Those PS reveiws are pretty good. (Thank you for NOT posting it though.) I was thinking of contacting Practical Sailer and sharing links with all of their reviews. The user would still have to buy the review and agree to NOT share it. They advertise pretty heavily with Google I noticed, which may have been what you saw on the site here. Still, it might be a good deal for them. My site gets a more traffic than the PS one, and usually shows up in the search ranking pretty well for a lot of different boats. I have no plans to do reviews myself. Although I've been told that I do need to create some sort of effective comment window for each boat. Relatively easy to use but still somewhat spam proof.
Another addition to my 'to do' list.
