I would say it depends on how strict the Consulate is with the I-134 because some want to see your last 3 years of taxes and make them all count, and some count just one year but in any case it doesn't sound like your taxes for 2005 show you are above the level. My advice would be to get a co sponsor just to be safe, but I'm sure someone else can offer you some good advice.
Good luck!
I agree!
When we filed our affadavit of support I knew that the estimated profit from the sale of our house would put us way over the required amount, but just to be safe I had my parents fill in an I-864 as co-sponsors. In the end we didn't need their affadavit at all but I'm keeping it until the visa is issued just in case. Never hurts to cover all the bases.
