[GreenKeys] would like to get some more 5-level tape

[epvgk at limpoc.com]

Looking for some tape appropriate to my 14 reperf and 19 punch. 
Down to a couple of rolls I think, so I feel like I ought to 
stock up a bit. 

I see some cases of 10 on ebay but the description says they have
a 1" core, and both my machines have 2" spindles to hold the roll.

Also, I've never been 100% clear whether I want oiled or un-oiled. 

anyone?
