What is my bike worth? Custom Kona Cowan

[JHart94949]

Ok, kind of a weird question but I have been building/putting my bike together for about a year piece by piece and want to know what some if the more experienced guys think my bike is worth.
So here is what I have:
-2007 Kona Cowan Frame (Hardtail)
-Manitou Minute Expert (100mm) fork
-BB5 disc brakes
-Deore Rear mech
-Alivio crank and front mech
-9 speed xt cassette with SRAM chain
-LX shifters
-azoic outlaw wheelset
-Kore r.a.c.e bars
-crank brothers eggbeater 2 pedals

Everything is new (less than year old) frame is an 07' but was new/never built up when I started about a year ago..I have about $1300 invested right now..what do you think its worth and I am just wasting time an money or should I keep making improvements/upgrades??

So I guess my question is...what should I upgrade next...I have about $1000 in the bike already. I was thinking crank

Sorry didn't proof read, hate typing on phone. I have about $1000 in the bike and just ordered wheelset for $280....so roughly $1300 when they show up....
