Used you could just about get a 1060 3gb, but that's quite a big card in comparison to what you had, so you'd have to check it would fit and your psu can power it.
If you need something smaller or lower power then a 1050Ti is under your budget, or if it's got to be really low power a 1050 (non Ti) would still be a massive upgrade.
If you want to spend a bit more and buy new a 1650 super is both small and pretty low power, or a 1650 (non super) is even lower power.
