I wish someone would share their knowledge of auction sales. I keep hearing decent numbers across the board for generics.
While there's a lot of private sales that never get reported (which makes sense if you're looking to buy more), the stuff in TBR auctions often gets tracked. A good place to start is the domain sales database at:
dnsaleprice.com
You can search by TLD, just click .ca and leave the keyword space blank. You can then check out sale prices (keeping date of sale in mind) to get a sense of what stuff has historically gone for. Here's an example of what it lists for the sales between 10k-100k:
HomeTheaters.ca $12,500 Jul 07
Theaters.ca $25,000 Jul 07
Hollywood.ca $13,550 Mar 07
CanadaComputers.ca $16,055 Jan 07
Delivery.ca $26,801 May 06
Financing.ca $12,000 Apr 06
Traffic.ca $12,902 Apr 06
Savings.ca $36,050 Mar 06
Searching.ca $31,500 Jun 05
Resto.ca $11,611 Apr 05
Blog.ca $20,201 Feb 05
Of course if you search for prices of 10k and under you'll get way more results than that.
