A little while ago I was searching for a low cost ~2kVA pure sine wave generator and happened upon
www.mygenerator.com.au. They had a good range including one called Cromtech Outback. I didn't end up buying one because I became distracted by other things, and they are probably sold out now with everyone preparing for the Apocalypse, however I'd still consider one if I was in the market for a low cost option.
I agree the Honda and Yamaha products are very good, and if you were planning on regular use close to 2kVA loading then go for one of those perhaps.
