Line Lock- Quality?

Biondo if I needed another one, good unit and good customer support
I've read "Biondo" in at least 3 posts in this thread, all good comments.
I haven't heard of Biondo, ever, but obviously that's my lack of experience.
I don't remember who made my line lock, but I know it's nothing "special". I've had it installed for a year and a half, but unfortunately no time to go to the track, and barely any time to drive my car, BUT I am aware that my "free time" has been none to very little, and that's having a negative impact on my physical and mental health.
The point is that I have had too many things that demanded my time, and I let "her" know that I need to do some things for myself...lol.
Whatever made me buy the one I got for the 65 GTO, I got the same kind for my Roadrunner, and I should be able to use it soon, even if it's on the deserted roads where I live to start out. I wasn't aware of any specific or special characteristics I could even look for to decide what makes one kit better than another!
