Well my two friends use these triggers and all three off us use vivitar 285hv's, I'm buying this setup and another vivitar once my pay check arrives.
The triggers are cactus's, their pretty reliable, work well, no ttl but your going to be shooting in M anyways. They range up to 100m according to the site but I'd estimate its less, probably 50m.
The vivitar is super powerful, easy to use (1 dial adjusts power from full to 1/16), but it has a pretty long reload time at full power (1/16 is pretty instant). Their reliable enough, I have to give mine a smack before I power up to get it to work, but its fine after that, no issues. Handy little guide on the side that helps you to expose properly. Whats awesome about these flashes is their so cheap that if you knock one over and it breaks its not really a big deal. You could easily get 2 vivitars, 3 Triggers, 2 stands, 2 umbrellas with holders, all for under $300.
Triggers: Come in double and single packs.

Flash: Retail is just under $100, you could easily find them for cheaper if you look, I got mine for $65 lightly used on here.

Other: Stands vary in size/durability, buy what you think you'll need. Umbrella's are hand for portraits and to diffuse/spread light evenly.
