I tried looking for a store awhile back, found Babana had offices in Bolingbrook but their warehouse is downstate.
I think your best bet would be to try ethnic areas with alot of Muslims like Burbank or Polish neighborhoods both on North Side and South west side of Chicago.
I see fortec dishes around my neighborhood, globecast too, saw a channelmaster dish just 6 inches of the ground next to a garage, most are setup for IA-5.
Call around , you might get lucky, and let us know if you find something.
Andrew which (owns) makes the Channelmaster dishes, is located in southwest suburbs, give them a call and see if they can refer a local dealer, even better it be nice if they had an outlet , you never know unless you call.
There is a place that used to be in Oak Park, they have moved to Des Plaines, they setup C-band dishes and might also do FTA Ku setups. try them out.
