I've given Maker a couple more chances and it's definitely gotten better. The delivery remains atrociously slow (I've never waited less than an hour and it's usually closer to 1.5) and the service is rude, but the biggest flaw before -- the crust/dough -- has been improved. It's a lot lighter now, but still substantial enough to support the weight of the generous serving of cheese/pepperoni above.
FYI, despite their best efforts to fool you when you call, they *do* in fact take credit for delivery. You may even have to insist because all they say is a terse "Cash on delivery." You just need to give the card details to them over the phone.
