Have a look here at some of the .co.uk sales results, I cannot remember seeing a decent .com geo on dnjournal for a while.
Perhaps it's because people are riding out the current recession and not succumbing to firesale pricing in this buyers' market.

I sold a UK city .net last year for a pretty penny. I'd say that both .net and .info are great alternatives to the .com.
hmm and does anyone know where I could find and buy a co.uk drops? also .ca/.au
Johnny24,
The most active .au aftermarket I can think of is NetFleet (http://www.netfleet.com.au). Drops are under the Snapper Auctions section of the site (https://www.netfleet.com.au/simple/snapper). NetFleet also sells aftermarket .nz domains as well, if you're interested.
Hope this helps.
Cheers,
Entropy
