Help me blow money on a lens.

[powerslave]

Alright, I have been itching to buy a lens for a while. I haven't owned any real lenses ever. I've used some good lenses and I know what a difference they make. My current setup is a great general purpose set up with a little bit of everything:

Canon XTi
EF-S 18-55mm IS
EF 50mm f/1.8
EF-S 55-250mm IS
430EXII
Certain filters/tripod/remote release etc.

I don't NEED any lens, I want something. To play around. I'm unable to decide if I want a telephoto/UWA/TS-E/Zoom/Prime. So now you see my predicament. :D

I looked over the following lenses and I don't know what I want:

UWA:
Canon 10-22 (Been on my list to buy for ever now.)
Sigma 8-16

Fast Primes:
Canon EF-S 60mm f/2.8 macro
Canon EF 85mm f/1.8
Canon 100mm f/2 , f/2.8 macro, f/2.8L IS macro
Canon 135mm f/2L
Canon 200mm f/2.8L


TS:
Canon 45mm TS-E
Canon 90mm TS-E

As you can see, I do not have a well defined need for a lens. I have all my needs covered by the lenses I own. I want a new toy. In all probability, I may end up with the 10-22. The single most annoying thing about the Sigma 8-16 is that it doesn't take filters (at least the regular ones), and that is a deal breaker for me.

I just want a solid lens to play around with, let's just call it a birthday gift from me to me. :D

Other than the 135 Prime, I have used all other primes that you have listed above. I would say go for the 85mm Prime with your eyes closed. You will NEVER regret it! :)

Manas ended up buying the 10-22, but as I told him on IM, go for the 135 next! :D

Yeah I kind of went ahead and got the 10-22. The 85 seems next on the list.
