Sourcing Triple Heat Sink (0mxj5)?

I just ordered the parts to do a double 330 PSU, new thermal paste, and I plan to flash my vid cards and mobo so I can start doing some overclocking. After pouring through the forums over the past 24 hours I went and looked at the part list and it seems I came with a single pipe cooler for my I7-3840QM and dual 680M spec'd rig. People indicated you could get the part for roughly $30 so I called Dell and they indicate that they no longer have stock and will no longer manufacture the triple heat sink for the M18XR2. I found some online for $71. Is this the best price I should expect?

Example:
Dell Alienware M18x Cooling Heatsink DP/N: 0MXJ5, 00MXJ5

 

i bought mine from them and received it less than 2 weeks ago, works great!! keep in mind pchub parts are all USED but it doesn't really matter for a heatsink and this is probably the ONLY place you will find one unless you get very lucky, unlike you Dell didn't tell me they didn't have this part they made me wait a MONTH and THEN told me

word of advice - get the express air mail, the part will most likely come from CHINA

 

Awesome, thank you! Ordered =)
