MAS is powerful, complete and wonderful to use once you know how. also i found the folks who install it and do the support are helpful and you can get particular things written for it. on the other hand, if you really study what it can do, not sure many people would need anything more. it rocks!

but i'm not sure - ask the MAS folks and your host - how many paysites you can run on a single server. i would think 26 would be keeping that CMS mighty busy of course, unless you're sharing content between the sites or all the sites are nothing but plugins, 26 paysites wouldn't fit on any harddrive known to man after a year of updates.
