I made my own with the following stuff purchased in Sydney Australia and in Aussie dollars.
1) 2nd hand CPU heatsink with fan $10 or free
2) Peltier for Jaycar Electronics $20
3) Artic Silver Thermal Adhesive $20 (this thing is enough to make 5 units maybe more)
4) 540 heatsink or cooper tubing piece $5
5) wiring, connector, and shrink tubes $5
Can be view in Windsor or EC. Not as pretty as muchmorestuff but it works better
