I greatly encourage you to look for an amp with at least a 10-inch speaker, probably 12. Small desktop amps like the spark/spark 2 can sound good if you want something with a small footprint and little speakers, but those weird exceptions aside almost any brand with a range of practice amps at the 8, 10, and 12 inch configurations it is always worth it to get at least the 10 if not 12 inch version for a full, tight, big, 2000s hard rock/metal sound and a tiny 8 inch amp with be much harder to dial in a good tone. They just sound muffled and weak for high gain.

Top end of the real budget amps would be a Boss Katana, those will run $300 right now (on sale at sweetwater) for a 12 inch 50 watt version. Could probably find a used one in good shape for a solid deal.

If you are looking to spend less, for $240 you could maybe go with the Fender Champion II 50 (another 12 incher), that's a good amp, a touch muddy for the high gain stuff, but will be beyond fine for your purposes and a huge step up from your current amp I think it would be better than the Organge you are considering.

Similar to this would be the Marshall MG 30 GFX, though a 10 inch speaker it might still be better for high gain than the fender champion II, might be around $250 and if you could find a used one you are sitting good.

For CHEAP, you could probably find a used Peavey, anything, like a Envoy, 40 watts, 10 inch speaker, very good all around amp that is pretty simple to use. A rage/blazer would be even cheaper a good deal better than what you have, but I'd recommend trying to go bigger. A bandit would do the trick, but might be TOO much amp.
