Hi there , i would say your best bet is to go for the Norco and then gradually build it up with new parts like bars, stem new brakes etc. and then wen u have a good spec Norco buy a new frame and then it does not cause you to spend all your money at once, and also you can buy good parts that you know will not break. The only disadvantage of this is that it takes time but it is satisfying when it is complete. I did this and now i have a top spec bike that i am pleased with and it doesn't appear to of taken a massive chunk out of my wallet ( even though when you and it all up it has!) I hope this help Sam x
