I'm assuming you're on PR-2s? Everything will be better than that.
There's a wide selection of ~1500g, 30-35mm deep, alloy wheels for your budget. Primes are super cheap but not sure it would be a noticeable upgrade - I'd recommend forgetting about those. Scribe is a good idea, but you may struggle with availability. Hunt wheels are OK too - at least the alloy ones, but on the pricier side and they're not better than others. Maybe have a look at DCR Wheels? They're not as popular so should have stock, good quality and decent pricing.
Alternatively, find a local wheel builder and have him quote you for something of that weight, depth, with sapim spokes and bitex hubs - should be within budget.
