From what I've seen, wellspring's pre98 bubbakush is top notch, they have some dead head og kush from the same grower but the current batch is a little wet.

The banana from releaf would be my 2nd, but I haven't seen much of it, they're still pretty new to me.

The Hatch in highlands ranch has great stuff, but I don't go there anymore, the last time I was there they had stuff for $30/gram and $75/eighth, total bullshit. He has that rich market though, so good for him.

Cannamart has bubba platinum, I'd say 3 on my list of the 10 or so MMC's I go to regularly.

I'm a high volume patient, so I don't pay more than $45 for a bag. I have no idea what you'd pay.

edit: I'm in south denver, and there are limited MMC's in douglas county. I don't have experience with delivery services, and craigslist is just horrible 99% of the time, but I've found good stuff there occasionally.
