Purchasing a new Colt SAA

[Sixshooter_45]

I'm contemplating purchasing my first Colt SAA and am currently looking at the following listings, I understand the differences between 1st, 2nd, and 3rd generation Colts but do not know if some the listings features of a particular gun would make them undesirable.

I plan on shooting it!

So please feel free to inform me as to what purchase and more specifically why I might want to stay away from purchasing one of the following.

Thanks for any information about these.

All of the guns on your list except one are third gens.  Any of them would be a great shooter.  The 2nd gen is nice but I personally wouldn't pay that much for a shooter.  Some second gens are collectible if they are in new condition.  Otherwise a Colt is a Colt and they will all shoot.  Depending on what you want to do with it a spring kit will make life easier and if you intend to shoot it in competion an action job is almost a necessity.

Even given today's inflated Colt SAA prices, those seem high.  Keep looking (everywhere you can think of), you should be able to find one for less $$$.

Don't take this as gospel but my research indicates and 3rd Gen with a serial number of S34xxxA or higher should have a removeable cylinder bushing.
I personally don't like gold writing or other commemorative markings and I think most commemoratives are not considered as desireable as normal factory guns by collectors.
I do see a problem with the last one. The seller says it was made in 2009 but the factory letter say 1999. The serial number seems too low for a 2009 gun so I think 1999 is correct. Serial number and pictures also indicate pressed in cylinder bushing not removeable cylinder bushing.
