right, well I think if you can re-use some partw on your old bike, you could afford a nicolai. 3 grand would get you a frame, fork shock, headset seatpost and pleanty more, then just use you drive train wheels and brakes from your old bike untill you can afford new stuff.
Nicolai make really strong bikes, you won't notice any flex and it won't brake. (if it does, then they fix it pretty much with no problem)
