The Hobby Lobby closest to me has a great selection of models. But their supplies leaves a little to be desired. It was mostly Testors paints (bottle and spray). They do have good prices on brushes, blades and such.
The Hobby Town USA that I went to, that is the closest, was a big disappointment. It was a small shop and mostly RC stuff. The scale modeling stuff was in disarray and made no sense on how it was organized. It was also only about three small shelves of paint and stuff.
The closest and most stocked Hobby Shop around me, that I have found is Wild Bill's Hobby Shop in Irving, TX. I am amazed as the amount of stock they have. A lot of it is RC and die cast vehicles. But they have a whole row (40-ft) of models stacked from floor to ceiling and a great selection of paint and supplies. However I couldn't find any PollyScale Clear Flat.
