Mine was 637 shipped. I don't think it is expensive for what you are getting.
Labradar 625, needs a mounting solution and batteries.
Magnetospeed V3 450, attaches to your barrel or spend several hundred on a mounting solution in addition to what was already spent.
Bullet seeker Mach 4 - 1089
FX Outdoors True Ballistics Chronograph - 1000
You are getting a lot of bang for you buck on the Xero, IMHO.
