You may find that to be perfectly serviceable. If you do want to check out other scopes, though, be sure to bring that one with you for as abaseline comparison.
I know guys who are happy with $15 to $30 scopes on their rimfires, and I've heard of guys who put $300+ scopes on their rimfires. Those scope mfgrs will take all of the money you're willing to throw at 'em!
