If I don't like spending around $300, I really won't like spending $500+.
There's tax, so it makes it cost more. Doesn't really matter where you buy from, eBay might be tax free currently. But buying from a store like B&H or the manufacture directly, there will probably be tax. Does B&H have tax? Not sure if they did last time I bought from them. They might now. States want their tax money, even if you buy from a different state.
