Give me a price range and I can work with you from there...I and my buddy are the MTBers of the town and pretty much support the LBS. We ride mostly urban (pretty hard), hard trail riding, dirt jumping, and north shore, and hell some XC too.
I'm on an upgraded 2003 Kona Scrap (dirt jumper series) and he's on an old Trek Bruiser 1. I have to say that both ar great frames with the edge going to Kona.
What I like about Trek:
great service and great all around bike
What I don't like:
they put decent components all the way around for the money so when you upgrade to a certain level... you upgrade everything because nothing is spectacular (IMO)
What I like about Kona:
Amazing frame
Great components mixed with not so good components so when you upgrade... you're halfway there already
What I don't like:
There are fewer dealers and can be hard to get ahold of.
To put in perspective what we're riding:
My Kona Scrap is now worth about $2200
Marzocchi DJII fork
SRAM X.9 all the way around
hussefelt cranks
shimano disks (may go to hayes HFX-9's)
Amazing bike
My buddy's Trek Bruiser: ($2200)
Marzocchi DJIII fork
Shimano LX/XT
LX cranks
Avid disks
My opinion... go with this:

It's a great bike with no major flaw up front... down the line you may want to upgrade the fork, shifting, and brakes to hydraulic but that come with time. If you have a little extra cash get the Stuff instead of the scrap. It come in at under $1000 and comes with hydraulic brakes. Here you wouldn't need to upgrade the fork either (unless of course you wanted to) and shifting would still need to be upgraded about a year or so down the line. To put inperspective what you would need for the bruiser... my frind doesn't have anything stock left on his bike. Go Kona.
Hope I helped... if you have any questions feel free to IM me.
