Good grief. A 1000VA UPS starts at close to eur400. Now, correct me if I'm wrong, but it seems to me that the whole VA-Watts thing is basically a matter of how long the unit can last in the event of power loss, right? Or does it affect something else as well?
In the seven years I've been living in Dublin, there's only been one blackout I know of, but it was localized and didn't affect me. So I'm not too worries about blackouts, so much as power surges and the like. Given that, I'm wondering if I'd be better off buying just a surge protector, since the likliehood of a blackout is very low.

A little bit more will get you a 'line conditioner' -- a surge protector
plus a transformer that steps low voltage up a little bit. This additional protection is a good thing to have. Utilities also have 'drops' in voltage as well as surges. This is included in a UPS these days, so you're actually getting three different systems in a UPS: surge protection, low voltage protection, and blackout protection.
You might also try searching for used equipment. After all, it's not like a UPS built now is dramatically better than a UPS built 5 years ago.
I know you can buy reconditioned UPSes from used computer dealers here in the US. Dunno about Ireland or the EU in general (voltage is standardized throughout the EU, right?)
