If you horse is really wide you can look into Thornhill or Duett. Thornhill Vienna you can buy under/around $1K new, for other models and Duett - used in excellent condition. Other suggestions would be M Toulouse and Collegiate (I believe both new around $1K), or used Passier, County, Crosby, Stubben (I'm not fan of Stubben though, but many people are).
