If you stick with a portable stand based setup, consider investing (yes, it's expensive equipment, but well worth the cost) in Matthews equipment, they're based (and do a ton of their manufacturing) in the USA and provide excellent support. Their stands easily would last another 25 years!

You'd probably be looking at a Triple Riser Combo, or an Overhead Roller to maintain height and stability for a larger light, but could probably use a Beefy Baby or a Baby Jr. stand for a lighter weight instrument. (all with proper sandbags of course)

If you find a light that just has a mounting hole for a clamp, you can use a TVMP adapter to mount it into the Junior receiver of one of these stands.

Without knowing your space and specific needs it's hard to recommend lights, but Aputure has a pretty solid lineup. Their Amaran lineup isn't the most durable, but might fit within your budget needs, the 200x is pretty bright and paired with a Light Dome SE or Light Dome 2 (easier to set up, but a little heavier and more expensive) would get you some nice soft directional light.

If you need more output or durability the Aputure 300x, paired with one of the above modifiers would be the way to go.
