Nobody's mentioned the fact that the Dewalt's greatest charm is the way it breaks down into very lightweight sections, none over 40lbs or so. Plus, it's water and spray catching tables are second to none.
I'd have no hesitation setting it up in someones finished bedroom.
I've no doubt the MK101 is a better saw, but that sucker is HEAVY and a pain to store.
I've had a Dewalt I bought used and it's quite well thought out and very well designed. No issues on mine in terms of durability either, I wouldn't judge it by some rental units at a low-rent Home Depot.
I'm assuming it's not that great of a HD as most around me keep up their rental equipment much better than that it seems the above poster found.
Around here they regularly sell off the rental equipment at much less than market value on a yearly basis. I've bought generators, cement breakers, tile saws, sheet brake, etc. from their rental dept, all much nicer shape than typical used and at lower prices than they'd go for used on CL.
