I've got one, but mine's not transparent. (I'm not disputing your opinion, just acknowledging the inconsistencies in the 219). Mine's a bit dark, and I found it useful on a number of brighter things (yep, guitar included) like female vox that needed to be tamed. As I recall (it's been a while since I've used it) mine has almost a ribbon-like quality to the sound.
I bought my 319 for $25...but I sold it for $150 ...what kind of a deal did you get?
Practically nothing. I got it in a trade giving up a $40.00 valued item.
