Not sure what possessed me to Google Altman but I did. I worked at 35 E. Wacker so the store was a popular lunchtime trip. I could not afford Nikon and Canon at the time so I 'settled' for Olympus. Bought, and still have, my OM-1 and OM-2 at the store. Also bought my enlarger there. I never felt rushed when shopping. I am under the impression the sales staff did not work on commission.
Shutan was the choice after Altman closed. Just recently went through a couple of boxes of photos looking for things to scan and upload and there were many Shutan envelopes. Take a peek at www.myimagecollection.com if you want.
I did visit Helix a few times but their location was not convenient.
