Profoto B1 is definite rock & roll level hardware. Profoto is the go-to system for people in the flash hire/rental business.
Yet after a decade and a half of almost evangelist level Profoto ownership, I sold off the lot a couple of years ago. The cost of ownership was high. High purchase prices and frequent trips to the repair shop took the shine off for me. So eight Compact 600 heads, two 2400 w/s floorpacks and all the modifiers and accessories were quickly (and easily) sold.
I now run with eight PCB Einsteins, VML's, and lots of staggeringly good value modifiers. They get shipped all over the place and have passed the tough-test. I like their very light weight, small size, power range from 2.5 w/s to 640 w/s, quick recycling and (so far) perfect reliability. An Einstein head is priced around the same as a Canon 600 EX-RT vs around $2k for a Profoto B1. PCB support is legendary.
Getting back on-topic, Profoto B1 vs. Phottix Indra is a fascinating comparison. Phottix are making some great stuff, no question. The Indra is probably perfectly fine, but I'd be looking closely at choice and range of quality modifiers, performance/reliability feedback and importantly, the standard of product support close to where you live. http://www.thephoblographer.com/2014/11/03/first-impressions-phottix-indra-500-ttl/#.VLxUSifOQZ0https://fstoppers.com/gear/phottix-announces-indra500-ttl-500ws-strobe-ttl-and-hss-37521http://www.lightingrumours.com/phottix-indra500-ttl-6267#.VLxbJCfOQZ0
We're absolutely spoiled for choice with flash gear now compared to just a few years ago. My best-buy for 2014 was a pair of 400 w/s Godox Witstro AD 360 flashes. Talk about great value. Godox and some of the other emerging brands may not have the street-cred of Profoto or Broncolor, but really, who cares? It's the credibility derived from the results you deliver to your client that counts.
