I don't understanding not waiting for what you want unless you've got a gig coming up and having that horn is critical to the gig.
Personally, I've seen and tried out two each of TK Melody altos, tenors and sopranos, and I do not care for the engraving. I don't like it on any horns btw, unless it's subtile, so that's just me.
I have a soprano Yardbird with full engraving. Looks like Japanese tattooing. I like it on the back of Japanese women, not on my horns. These things are personal and highly subjective. Like Brian writes, the engraving definitely does not recess with time, so if you don't want one fully engraved, don't be impatient. Order one without and wait for it to come in.
p.s. either I or some others need to re-read some of the posts, starting with the OP.
