Where to buy, good deals on UPS

[bunchofkeys]

Currently running an APC 1500 watt UPS, which is ok, the batteries were changed last year.
But had another power cut today, although brief, and i could see the battery life deplete at an alarming rate, so it's time to upgrade.

Apart from the likes of Amazon, where else can i look to find a good deal on a new UPS.
Will be looking at a min of 2k watts, to run in conjunction with the 1500 unit i currently have.

I don't have a rack yet, but i wouldn't rule out a rack version of a UPS, as i will be looking at building one in the near future.
The current UPS is a tower.

I got one recently from a company called Riello which was much cheaper than the equivalent APC, and a bit of research suggests that the company makes some pretty gnarly UPS products, so is probably OK.

My APC died, but if it’s just capacity you are after, replace the batteries with 80 Ah car versions and it will run much longer.

We've used OnLiTECH before and they've been very helpful and reasonably priced.
