I have a Crate Stealth 50 also, so I know the tone you're getting from it.
I'm not sure if the ones on your list really fit the 80's metal vibe; well at least the Laney ones. Those bring to mind more of a 70's metal early Black Sabbath tone; especially the 30BL. That one is in the Supergroup camp which is what Iommi used back in the day.
As other's suggested a JSX or XXX is a good choice, but it will be different from your Stealth. They're more American voiced than British voiced. You can add any of the Peavy Ultra series tube amps to this list. You may even be able to find a Peavey VTM in your price range also. The 5150/6505 series amps are great amps as well. These are all 80's metal personified, but American voiced 80's metal.
The British voiced amps will be what you want to match your Stealth, which is hot-rodded Marshall. Probably the best choice in this camp for your price range is a JCM2000/DSL100. If you look you could probably find a TSL for a few dollars more. Do some research on these before buying one. I think it was the early JCM2000 models had issues with bias drift. It was fixed in the later production years though. Someone else may be able to chime in on exactly which ones to stay away from.
Another overlooked option in the hot-rodded Marshall camp which you can get dirt cheap is a Peavey Windsor. The Windsor is a straight up copy of a JCM800 and pretty reliable. Put a Tubescreamer in front and you have 80's thrash metal all day long.
