Well, I think I have come to a decision, partly made by me with the help here and partly made by the fact that I think I lost out on one anyway.

Since my Tammy isn't selling, I am going to keep it and not get the current 17-55mm that is available. For the amount of times that I need it, it will suffice along with the 50mm 1.8 II (odd little lens btw).
I messaged the guy that is selling the 135L to see if it was still available for the lowest price he said he'd sell it for and my message was ignored so I think he is now going for the highest offer. Of which, I do not plan on going any higher than $825 and I don't see any others available.

Well, that was fun! Hmmm, now what should I buy instead!?
