Dave Willo and I may well have been the first people on YD to buy a Salvo, when I bought a 21W direct from Barry Miller at the end of 2004:
Story
I know Mark and I were the first people to buy a Salvo HID from Phill when he started NikNaks. At that time I bought a 10W as a backup. I used it a couple of times and later flogged it to Nick (Frosty). I'm guessing he's still delighted with it. I never used it as a backup as the original has been very reliable.
The only time it needed attention was when I discovered a couple of weeks after I'd done it that I'd cut through the cable and the canister had flooded (the dry lids stop this now). To cut a long story short, I fucked the battery and Barry Miller went above and beyond any expectations to sort it for me.
I would have no reservations about recommending a Salvo and with Phill's £100 discount offer I'd say run, don't walk to place that order now.
