Yes, it wasn't too bad, they had a decent amount of HO and N gauge on display, but nothing like what I would like to see from a model shop - they sell cameras and plastic kits in larger volumes. I got a few nice modern HO Gauge locos from them at a more reasonable price than being sold at the only real UK seller now. But nothing that was massively cheap, especially with the £/$ exchange rate being as low as $1.25. They are really friendly and it might be worth dropping a message ahead of any visit if you wanted to check what they had. They did have a O Gauge SD70 that peaked my interest, but after spending what i did on a handful of wagons and the three locos, I was happy I had enough for that visit. I did buy around 4 months of issues of Railroad and Railfan, plus Railroad Model Craftsman to stave off the UK prices.
The other place I visited was Zitnik Trains south of Tampa. This would possibly better suit your desires. They had half a shop full of oversized new and older stock and while i felt the price of HO Gauge items from more than a few years ago was expensive, I did not pay much attention to the larger scales. after a 90min diversion, I only left with a couple of steel signs for the wall and four packs of grade crossings from Woodland Scenic, which i know are rare at the best of times. I won't go back and even the wife was less than impressed with the trip there - but we used the Publix opposite to stock up on water and toddler friendly food for the day!
Cheers
