Your best option in that price range would be to look at used horns. Don't get too caught up in how the horn looks. There are lots of pretty looking new tenors for sale under $1000 and most of them are junk. I learned on a Martin Indiana. It was a good sounding, nice blowing horn, if a little old fashioned in its keywork. They go for well under $1000 and are more than just a student horn. Elkhart Conns made between 1955 and 1969 are good intermediate level horns that can be had for between $500 and $1000 depending on condition. Just be sure it says "Elkhart, Indiana" on the bell. You might be able to get a used Yamaha YTS-23 for under $1000. They have a reputation for being well made, reliable, and easy to play. If you MUST have a shiny new horn, Kessler, CE Winds, Walstein, and Antigua are solid companies with student tenors for around $1000.
