Patterns and prices vary wildly. I got granite 2 years ago and my wife and I picked a funky, interesting pattern that cost a bit more, but it doesn't look like the 'safe' patterns that builders pick when they put such counters in tract homes. It has sparkly stuff, black bits, odd shapes, etc. and when the sun hits it, it looks different every time. I was not a big fan of granite, but I enjoy this more than I thought I would. We have a bland, 1968 ranch style house, so it adds something interesting to our place.
Go to a large granite place and look at all the patterns. There is a ton of stuff you will never see except in custom homes and stuff that looks like it came from Mars.
One mistake we made was finding a nice countertop pattern at a great price, and then waiting 3 months to make up our mind. By the time we circled back, that pattern was gone from the quarry, never to return. So, we found something more expensive and bought that. So, if you find what you like, don't wait. We used Planet Granite (which I think operates in Denver, too) and they offered a thick, nice, 18 ga. stainless sink (what we wanted) and installation went basically as it should have.
The care requirements for granite are not onerous - either spray it with a sealant once/month or pay up front for a lifetime coating. We spray it once/month and it has been fine.
