Cactus + Vivitar 285HV

Any idea where can I find the best price for this two items?
I would like to get (Vivitar 285HV)x2, (Cactus Receivers)x2, and (Cactus Trigger)x1.
Should I get backups of the Cactus receivers and trigger too?
What else I'll be needing to set up this two flashes off camera?
Any store sells kits that include these items?

I have seen the Vivitars going for $75 each on Amazon, dont know if that is normal price or not though...

Sounds like you're trying to setup a stobist kit. As for the flashes, you should check craigslists in your area - you may find a good deal. Also, there are other inexpensive triggers on ebay, but you may need to purchase the hotshoe adapter separately.

These folks have put the kits together for you ... http://www.mpex.com/pa​ge.htm?PG=Strobist%20K​its. Budget dictates how deep you go!

You also may want to consider this if you find the flashes and triggers ...
