Here's a scan of the v500, ilford xp2 (120) film and silverfast SE. I am not entirely sure if I am happy with the v500, I get a lot of blowouts and silverfast does not support ice.
If you are getting "blowouts" that aren't in the actual film, then you aren't making the correct pre-scan software adjustments.
I don't have a v500 here to confirm but are you sure Silverfast doesn't support ICE on the V500 and thus you just need to change a setting? I can't confirm because I don't have access to a V500 at the moment but even if Silverfast doesn't support ICE, that is a Silverfast issue, not a V500 issue.
Yes, you can get a better scanner but it is going to cost you a bunch more money. For the price, the V500 does a pretty admirable job. There is a learning curve though so take the time to make sure to find out how to get the most out of the scanner.
