Couldn't agree more with the majority of the replies here. A MM cob is a pipe with a reputation and you know what your getting. You could even go a step up and get one of the cobs with upgraded stems, like the Kingston Judge or Emerald - both are incredible cobs that I keep multiples of.
A basket pipe is a gamble. Like someone else said, the biggest factor is are you able to inspect it in person, and is the shop a quality pipe shop or a vape shop that sells pipes.
Personally, I'd buy a MM cob with the upgraded stem and if I had the spare change, I'd get on ebay and buy a factory pipe or estate pipe. You can find Medico, Grabow and the like for 15 bucks or so on ebay and again, you know what your getting.
