I think it all depends on what you want if for.
I use an MM2 with the 25 x fixed eyepiece. That suits me fine, because I dont tend to stick myself in one spot with a big scope and let things come to me. I like to be out and about and the MM2 is great because it slips into my jacket pocket and if something is too far for my bins then I have the scope.
But if you are more inclined to do less walking around and want a larger field of view and brighter images then the MM2 won't suit. It's small size means you can pretty much always have it with you but the size, glass etc does mean that it won't compare with larger and more expensive scopes.
For me it does the job for what I require out of a scope and I chuckle at the big boys lumping tripods and 'bazookas' of scopes around, but then again I guess they chuckle inwardly at me with my pea shooter of a scope
