Liquid Nitrogen Cryo Spray Guns

There's a bunch of LN2 Spray Guns on ebay but... something kinda dangerous like this I don't trust to manufacturers that don't have brand names - kinda like how I wouldn't buy a firearm from an anonymous seller!

The Secret

A dermatologist is going to charge ~$300 for a cryo-surgery visit.

The equipment they use costs about $300 +/- $50.

See where this is going?

Criteria

Basically what I'm looking for is something that:

• has a pressure release valve (no explode)
• is a reliable brand name
  • is US-based / US-distributed
  • available direct outside of ebay / Amazon
• can hold LN2 for several hours (300ml, 350ml, 500ml)
• has spray nozzles
• has a release trigger
• affordable-ish (~$250)

Considerations

Probably better to:

• buy a smaller cryogun (300ml or 350ml rather than 500ml)
• buy a 3L to 10L dewar ($130 - $200) for extra capacity (rather than paying almost as much as a dewar for an insignificantly larger sprayer)

Candidates

• US Solid ($200): https://ussolid.com/liquid-nitrogen-sprayer.html
• Skrilix / dE ($250 - $300): https://www.skrilix.com/product-category/cryogun-sprayer/
• Strive / Basco ($220 - $325): https://striveindia.com/?s=cryo+gun&post_type=product
• BryMill ($700 !!): https://www.brymill.com/products/starter-package
  • https://www.justmedicalstore.com/catalogsearch/result/?q=liquid+nitrogen

Non-Candidates

• ebay non-brand ($160): search "cryotherapy dewar" or "cryo spray gun"
