Guys, thank you all for your responses.
Considering that I'll have to drive about $750 miles on torn boot, I'm strongly considering the complete GKN CV joint assembly.
I found it for $199 delivered from reputable online place with 2 year warranty.
I've also read 37 page long thread and it's going to be very helpful.
Thanks all!
