Blackburn Piston

I bought my inexpensive Inline-brand floor pump about ten years ago, and I am getting some leaking when I pump my tires. Not all the time, but enough to make it frustrating. Also, I have the common problem of the pump head being jammed sometimes (not allowing air into the valve), until I let some pressure out of the tube, first. I am looking for a higher-quality floor pump, and am looking at the Blackburn Piston 2 http://www.blackburndesign.com/pumps...l#.V5wDqLWYKM0.
It is cheaper than some of the nice Lezynes I've seen and it appears to be be good quality. I want something that is definitely a step up and worth the money. Fifty to seventy dollars is not unreasonable for me. I basically don't want a pump that leaks.
Has anyone used the Blackburns or heard anything good/bad/mezza-mezza about them?

I had a Blackburn for many years, I have no idea what model it was now, I took it to work and we used it there for a long time, I think I eventually gave it away when I transferred. Everyone that rode and worked where I did would come down to use it so I gave it to a guy in the next office down. He is probably still using it. In other words I think the are great.

It looks like the Park pump I have, except the Park (PFP-7) has dual holes in the handpiece: you don't have to switch rubber plugs to go from Schrader to Presta of vice versa. That may be good or bad (the single purpose Blackburn nozzle may fit better for all I know). I like my PFP-7 and agree it's worth it to have a good setup for your tires.

Done anything with the plunger cup? My 30 year old Silca and Medai have leather cups

I keep them greased , with Boot grease (Or bearing grease) and they work fine, still.

"... pump head being jammed sometimes (not allowing air into the valve), ...

The pump head could be crooked, interfering with the valve stem's movement.
More likely the valve stem getting stuck, not a pump problem. Standard procedure is to "burp" presta valves before attaching the pump to make sure they're not stuck.

After pumping, the little presta nut barely has to be tightened, since air pressure does all the work of closing the valve.

Also, as fietsbob mentioned, air leakage can often be fixed my regreasing the plunger.

I had a Giant brand floor pump, and the rubber gasket in the head wore out and would not seal against the valve. A local shop was a dealer, so I asked if they could get a new gasket.
"No, but Giant has a lifetime warranty"
so I got a brand new pump ! It's a nice one too...

You know, it's interesting that you should say that, because I have been having trouble with the leather plunger cup on the pump of my back-packing stove (M.S.R. Whisperlite). I lubed it with Zoom-Spout (supposed to use mineral oil, but eh.., feh...).
I really had no idea that floor pumps are serviceable, and that they contain plungers and o-rings (gaskets). I'll tear this one down soon and take a look.
It's funny, also, that you mention "boot grease". My hands smell of Huberd's as-we-speak, having just emptied a can of it this afternoon onto my Dunhams.

I fixed my floor pump by purchasing a new pump head. Ninety-nine cents and free shipping on Ebay. (It wasn't the piston at fault).
