[TVARC] RIGblaster vs Signalink

[Frank M]

Looking for feedback on the two external sound card devices. It is about time I move on but would like user opinions.
As I see it, the RIGblaster Advantage advantage (you like that??) is FSK RTTY and true CW.
Only think bothering me now is RIGblaster Advantage is a 2011 design and I see no evidence of hardware improvements.
Any comments would be appreciated.
