Cant help you find one im afraid but regards money manuals tend to be cheaper than DSG (reflected in them being £1K cheaper from factory than DSG cars).
I would be looking for 08 plate as there are only half a dozen 58 plates that I know of as most were regged before september 2008 and from June/July I think Pirelli was available anyway, well my car was build number 2235 and reg'd in mid May 08 so only 65 after mine as there are only 2300 in the country.
Price wise, depends on seller, some ask fair money and some ask stupid money, I paid £12k for my own Candy White Edition 30 08 plate 5dr DSG 39k FVWSH and it had every option on it except folding mirrors, bluetooth and cruise control (cruise was retro-fitted for me by fellow member eddie_nl for under £100), I dont want/need BT or folding mirrors, I bought it in late october / early November (2011) and seller needed to sell and I drove a hard bargain, do your homework and go armed with facts that was when sellers is sticking on price and says "Its worth every penny" you can say "Err no it aint here are 7 that sold in last 6 weeks for much less!!"
Average miles for 08 plates will be around 46-48K (Basing it on average 12k p/a)
I see lots of 07 platers asking 12.5 to 13K and they stay for sale a while
I would aim to pay less than £13K (12K ideally)
Keep checking Ebay, Autotrader website, British Car Auctions website, Pistonheads, Gumtree etc and you will find your car eventually (it took me around 5 months fro start to finish).
