Welcome to Commoragh!
For the cost of 100 pts, the Talos ROCKS!
But that's my opinion. If not played through a WWP, the Talos is generally too slow, and at 1000 pts, you'll probally be better off feilding another sniper squad at that amount, but, on the other hand, since you do want a shooty army, they're great for going to deal with close combat units that can really, really, really get on your nerves. *cough* Wraiths *cough* Its a possible 7 attacks launched off from one platform that is a strength of 7, with 3 wounds, and can take a beating from long range equipment.
At the moment, I'd stick with Ravagers and Scourges for a shooty army, and as needed, feild the Talos.
