What kind of trumpet should I buy?

I currently own a Yamaha beginer trumpet. I wil be in 8th grade this year and I've been told I'm due for a new trumpet. I am in the highschool lesson books so that might give you an idea of what level I'm at. I'm not sure what kind of trumpet I should get. Does anyone have any recomendations as to what kind is best? Also, is it a good idea to buy one off of ebay?

What kind of trumpet should I buy?
Unfortunately, buying a trumpet is alot like buying a car. You cannot come into a car shop and say that all fords mustangs are best and blindly choose one out of them all. You have to look at the entire package before you decide AND you MUST play on them before you decide. In reality, King, Bach, Yamaha, Conn, Selmer all make great instruments and at the beginning/intermediate level it REALLY DOES NOT MATTER what model horn you choose. But DO LOOK for these things: the way the valves feel when you play runs on them. Does the valves feel sticky? if they do put some oil on them and try again. The valves should feel comfortable and should not catch on anything. How balanced the trumpet feels in your hands (especially true if you play in a marching band). Is it bell heavy? or valve heavy? Do the spit valves cover the holes entirely. Nothing can ruin a horn quick than having an air leak in it. Then check the slides. Do the slides pull out with ease or do they catch? Then you should play the horn. (play a chromatic scale from the lowest note you can play to the highest) does the horn respond well to every partial on every key? And finally look for cosmetic damages. Is the horn in good shape? how many scratches? dents. . . I personally bought a beginner Yamaha horn when I was young trumpet player and it played great all throughout middle and high school. Unfortunately my valve casing and valves started corroding. In college I switched to a (state owned) professinoal silver Bach Strad, it played great but I did not like the brilliance so much so I switched to a gold/yellow bach and really liked it. Ive tried Jupiter and liked its sound. The general rule of thumb is the heavier the trumpet the darker the sound but the harder they are to control (pitch and partials). But once you get used to a horn then these things do not bother you. Many young players want to think that there is a golden model that makes you sound like a great trumpet player, but the reality is the trumpet is just the tool to help you convey the music to the listener. Its not the tool itself but how you use it.

Reply:I recomend anything Yamaha or dynasty. I have bought instruments on e-bay before. You can get great deals. Just be sure not to get a no name brand or anything made by TriStar.
Reply:ask your band director
Reply:try a Stradivarius I am not sure of the spelling...but my husband has one and the sound is so pure. (I know it is a violin, but trumpets and coronets too) I have had good luck with stuff I have bought on eBay...bought a set of wooden flutes, 8 of them for $150.00 and they are wonderful.
Reply:Kohn.....they are very nice with a warm sound, a very common and practical choice.
