First make sure you didn't buckle the frame as well.

Check the downtube behind the headtube and see if it's bent.

If it is you've compromised the frame and jacked the geometry and it's probably better to replace the frame/bike.

For a sub-$300 bike, I'd probably get a $50 chrome chro-mo 1" threaded fork, as that'd look pretty sweet with a white frame, but they've got them in black as well for about the same price. (If you go this route, make sure you get one with the right steerer tube length).

Assuming that your frame is undamaged, and you want to go threadless, you're still not going to have that many choices in a 1" threadless fork, as most threadless forks are 1-1/8", and the ones that are available look like they cost about 1/2 as much as your whole bike.

That said, if you really do want a 1" threadless fork, you'll need the following;

1" threadless fork

1" threadless headset

1" threadless stem (with the other end sized to fit your handlebars).

1" spacers

hacksaw / pipe cutter (to trim the steerer tube).

Good luck!
