Most wholesalers carry generic 1 1/8" steerer forks with bosses for 'V' brakes and no suspension for 26" wheel. Your LBS will be able to get one in for you, pay £30 maximum for that in the UK and expect it in for you to collect in a week. (Most shops don't carry such items, just posh forks).
You will need to cut the fork down, this is simple enough and gives you the option to stack up washers on the headset for the bars to be at the height you want.
Typically replacement forks are painted black or chrome plated. Black paint will probably last better than chrome.
For what it is worth I would avoid a second hand fork. You don't want to find out that it has crash damage.
If you do things through your LBS then you are in a better position if you need help getting that lower bearing race fitted.
Avoid suspension unless you are willing to pay real money. Forks with damping etc are really horrible bits of engineering even though they are seemingly popular.
