Sean,
If you find a 210, it also uses the 58mm filters (they also match some of my Canon lens) and is nice to have - I have a 55,80 and 210. Don't forget to pick up lens hood for these, I use it all on a nice, for it's age, 645. Have been looking at the Super, but holding out for one of those killer deals. Congratulations...I think you will love it.
