I would call DGE in your area. No, they are no longer brick and mortar, but for those of us who remember their store (beautiful gas supply house), they are still awesome, and the source for about half of my purchases.
Although LeisurePro transitioned smoothly from B&M and catalog to online, I don't shop there. No real reason, I just don't. The first store I remember making the transition well was ScubaToys in Arlington, TX. I don't know what happened to their online presence, they seem to have faded. I still buy my Purple OxyCheq wings from them if they have them. Otherwise it's John from NE Scuba Supply, who also carries all of the obscure OMS valve kits for my ancient doubles.
