It all depends on your budget.
For just trumpet recording, a minidisc and a good mic works great.
I mainly use the MD. But when i need i use a boss digital recorder like this :

I did a quick search on ebay and found this:

Once i have it recorded i take it into soundforge 6.0 (sony now bought the program and has releases sony soundforge 7.0)
Then you can do wahtever u want, and burn it to a cd.
Thats about all i know, not sure on brands, but a good digital recorder with good mics should be what you need.
EDIT:
Actually somthing like this might work well also :
