I'd give it almost a zero chance of being repealed, even a fair number of Republicans are against doing so. (For example, Ron Paul. The subject came up when talking to Newsweek, I think.) Most people assume they're illegal already and most gun owners I meet either don't care about it or don't think the ban should be repealed.
If it were repealed, then I'd think the transfer tax would skyrocket. In 1934 the amount was $200. Adjusted for inflation that's $3,265.72. If your goal is $1000-$2000 machine guns, then I don't you'll ever see that, even if the ban is repealed.
