RefurbStore: Good and Bad Opportunities

Once again, the RefurbStore was filled up with opportunities, among them represent good deals, but other ones should be avoided as much as possible.
Here's what we found on the French one:
The iMac 17" 1.83GHz Intel Core Duo /512 /80 /Combo /GMA950 for 1.079.00 Euros. This is the iMac Core Duo Education, available for the public only 5 days before being removed from the store.
These offers, which anyway are only available on the French market, are simply too expensive because its education price is: 959 euros... and on the same RefurbStore, one can get an iMac 17" 1.83GHz Intel Core Duo /512 /160 /SD /ATIX1600-128MB /BT /AP for 959 Euros..
Other iMac models might not be really good deals when comparing them with the new Core 2 Duo-based models.
The good deal might be the Mac mini Core Solo available for 479 euros, and even the Mac mini Duo 1.66GHz equipped with a SuperDrive and larger HDs.
To conclude, be careful and do not only look at the price (whatever the refurb store and the currency): Refurb Store
