Sounds like you are a newbie like me. I've also looked into the 26m and 26x but after hearing two very different arguments like you I have decided to take another route.
Try to partner with someone who already owns a boat. Offer to pick up a portion of the monthly fee's in trade for use of the boat. this way you will get a true idea of what it really costs to own a boat, you'll learn a lot about sailing and what you like and dislike.
What I learned in my first year: When things get bad they get bad quick, The ocean is something to take seriously, small boats are fine for ocean passages if you are very experienced (which neither you or myself are).
I see that you are serious about researching the boats and I give you big props for being smart about it. Maybe post your area and your schedule and one of these nice sailers will show you the ropes, then you won't have to ask if the macgreggor is good, you'll be able to make your own decision.
