while in NYC go have a look at B&H photo. but be careful as it always cost me lots of money! i am in the catskill mountains of NY. about 1.5 hours N of NYC by bus. if you would like to see some rural NY PM. me. we are having a Large Format get together on sept 15th if you are interested. you do not need a LF all are welcome and it is a good time. this is our 3rd meet up. check here for more details http://www.largeformatphotography.in...714#post269714
you can carpool if you need.
i use sams club for my processing. it is cheap and well done. my lab is particularly good cause the employees are photogs and they process 120 in house! they also take extra care in cleaning their machines. they are very "pro" in their workmanship.
