I have a 430ex and a skyport wireless radio slave. I want to add a second light to this set up and I'm trying to find the best/ cheapest route. What do you think of a vivitar 285HV http://amazon.com/gp/product/B00004...&pf_rd_t=101&pf_rd_p=320448901&pf_rd_i=507846 and a wein slave http://www.amazon.com/Wein-Peanut-Photo-Slave-Range/dp/B0000C7HR9/ref=pd_sim_p_title_6 I will be primarily using the set up either indoors or outside at night. Do you think this would be a good set up? It says 100ft range indoors but when I am outdoors in the darkness of night it should have a pretty reasonable range correct?
