Which timing belt kit ?

[RED87]

Ok so I got the e30 a month ago and I feel really nervous driving it around since I haven't done the timing belt. The guy last did the kit and coolant hoses in september of 14' . the odo is broken and was broken then but he knows forsure that it was maybe 20k miles since then. . .
I called a few local shops (socal-riverside) and the place I felt most comfortable with charges $710.00 to do replace the belt w/ tensioner and water pump. 2 year 24k warranty. . is this normal price ?

and now back to the original question.. if I do the kit and everything myself, which kit should I go with ?

this one from ecs tuning is 128$ and comes with
