I would be wary of buying a kingpin, they can't seem to give them away. Might be a nice bike, but the resale is bad. If I were in your shoes and had the money (and was going with victory), I would look for used vegas or 8 ball. Nice style. Good prices.
Around here I have seen 01-02 lowriders between 10.5k and 11.3k advertised price. Fatboys and heritage usually get more. If you want a fatboy with different wheels, look at heritage and deluxe (I have a deluxe). They are all FL front ends.
I have been disappointed in triumph offerings, I keep hoping they will come out with a 1200cc+ motor in the bonneville america or speedmaster frame. That would be a nice bike. Allways liked the speed triple, but I think I would get in big trouble if I had one.
Motorcycle trader has alot of bogus price listings, check ebay to see what they go for. This has been the best indicator of price I have seen. If you have an account, you can click on the completed listings check box on the left and look at the completed transactions (in green). As always many think their bike is worth a mint, reality is that prices on used bikes have been dropping heavily in the last 3 years.
I have reciepts for my bike showing the previous owner (who bought it new, 05 deluxe) spent 24k. I picked it up 14 months ago with 12k miles (motor upgraded at 8k) for 14k. Just goes to show you if you look hard enough, you will find a deal. I bought mine in the same town I lived in. I had 8 months factory warranty when I bought it.
Good Luck
