They make some fantastic equipment in both N and HO. My HO AC-12 from them was one of my favorites, EVER. I had one of the original ones which was under-motored but looked and sounded awesome. I re-motored it and it could pull stumps.
Fortunately they corrected this issue on later releases. That however is the only flaw I have ever known from them. Plus I believe they have some of the most reasonable pricing in the market.
