FS: 5x 68/4500 Ninja and Guerrilla Air tanks

Selling these great condition Ninja and Guerilla 68/4500 tanks. They are working when they were last aired up but they NEED to be hydro'ed. There is approximately 5 years left on their lifespan, so please consider this when purchasing. All of their born dates early 2010, that leaves them with 5 years remaining.

They don't have any sort of physical damage. Some do have cracked regulator gauge lenses as you can see in the pictures.

Asking $25 each or $100 for all 5. Shipping should be around $10 a tank or about $25 for all 5. But I would prefer local pickup in Waterford, MI. Paypal f&f welcome but once again local cash would be best.

Shipping will be via USPS or UPS with tracking.

I have plenty of references including ebay/heatware feedback.
