WTB: ACT 2100 or 2600 Clutch or similar?

[mdost03]

I was told I probably have a bad clutch in my car so looking for cheap options for a nice upgrade.

Symptoms:
Doing a 3rd gear pull to log and when shifting to 4th gear was having problems going in. Finally got it in and then couldn't go back into 3rd. Limped it home in 4th. Car will shift gears when it's off, but once it's started, won't go in any gears. If you put it in 1st and start it, car will move forward (with clutch pedal pushed down) like if you had the foot off the clutch pedal.

Anyone know where I can find a cheap one at? MAP sells them for 310-400 for a brand new one, but looking for a cheaper option.
