[Closed] Two separate questions

Q1

I am the unfortunate owner of a 2011 Yeti 575 which is an awesome bike, Hence i hear you say "why unfortunate". Well on buying the frame it was pretty much brand new but for complicated reasons (no its not stolen)it is considered secondhand. Now the unfortunate bit:- the break mount cracked, a hair line fracture running in a rather odd direction, not crash damage i might add! So i set about looking into a replacement rear triangle. This turned out to be £599 which was for the new 2013 fully aluminium (a straight swap) and if i wanted the original alu/carbon job it would be £700. Now knowing the second hand value of the frame is only about £900 in almost mint condition i thought this was probably not going to be cost effective. I decided to get it welded instead, the welder is an excellent and highly competent chap who really produced an excellent repair and built in a little extra reinforcement.

Now I've been riding the frame now for about a month, and i'm considering selling the whole bike. What would you think it would be worth? the welded area has been resprayed and well blended in.
I'd be interested to know peoples thoughts on prices for a full build and the frame, the full build consists of full XT dropper post, renthal stem, chainring and handle bars, brand new ethirteen xcx and sun ringle wheel set as well as 2.4 and 2.2 conty rubber queens in black chilli compound. Also any thoughts/ideas on the sorry story

Q2

If i decide to sell i'm thinking of going for a mass produced job and get away from the "boutique", I recently became a home owner which has changed my bike cash flow situation dramatically. A good friend cracked his rear triangle on his enduro, which was second hand, specialized sorted him out with a replacement for £200.

One of the bikes i've been looking at is the new norco sight killer b3 at £1900 it seems a great buy with some decent components although the rear shock looks a bit ropey. Anyone got any experience with evans cycles as a customer? or with the new norco 650b trail bikes? i race a bit in gravity enduro events, alot of people are saying 650b will be the way to go.
