First off, congrats on selecting THE handgun of the century in the 1911.
Of your list, I would say the Taurus has the best "bang for the buck". It's a good pistol, with a lot of the key features, for not a ton of dough. Taurus has a lifetime warranty ( though customer service is spotty according to reports ).
Here is a report, including the one, lone downside, that one of our members found about the PT1911.
If you have the money to step up to a Kimber, I would do it, because I think they are turning out a great product, but given the price range, the Taurus is a good second choice.
Para bothers me because they produce their firearms in Canada, can't sell to Canadian buyers, but don't do anything to change that fact. That bugs me - they should be working, as a company, to reverse Canada's back-ass gun laws....
