Does anyone know where i could buy a refurbished benjamin discovery or Maximus or just a used one im trying to sell some things to be abel to purchase a PCP 
again trying to sell if any of you has one that you would like to sell let me know but i understand if you cant hold it for very long could take me a wile to sell my things 
but i cant find any sites where they sell used airguns
 
Another practical fill set up is a scuba tank. That is, if there are dive shops or paintball shops in your area that will fill the tank! Check this out BEFORE you buy a tank! That being said I got a year's worth of shooting my Discovery before I needed a refill on my scuba tank. The fill yoke and hose will cost between $50-150 depending on the quality.

Okay thanks John :) luckily my Discovery is coming with a hand pump and the TKO Muzzel break :) got a awsome deal on it 
$350 how is your discovery holding up John have you had any leaks ? i also was wondering when they need O-rings replaced if you have had to is it pretty easy to do ?
i watched a video on a few others looked easy enough ? we have one Paintball shop about 30 minits from my house to :)
 
I actually owned a Katana which was a Discovery based gun sort of a notch up from the Discovery and a notch below the Marauder. It was my first PCP and I liked it but got frustrated with it and eventually sold it after getting a Marauder. It was pretty accurate and light with a nice trigger. Never had any leakage problems, got around 25 good shots on an 1800 psi fill.

 
No-it never really caught on, you'd have to find one used. It had a Marauder trigger group which was very nice. A common mod for the Discovery type guns is to use a Marauder trigger group. Not a cheap fix though, and you also need a spacer between the air reservoir and trigger cause the Marauder air tube is a larger diameter. My Katana had a good barrel but would shift POI between fills.

In the pic you can see the spacer.
Congrats on you new gun!
