Hello, i was looking through the search function for some info on hydrualics and dump trailers etc but still need some help. What would be the difference between these two Power Packs.

The first is from Princess Auto in Vancouver, it is
Flow rating @ 0 PSI - A Single acting
Flow rating @ 2,500 PSI - 2.8 GPM
Relief setting (PSI) 1.3 GPM 2,500
Relief range (PSI) 500-3,000
Reservoir size (gal.) 0.75
Ports #6 ORB
PRICE 449.99 Canadian, (on sale for $400)

THe Second is from Dalton Hydraulics from ? (somewhere in the US)
Operation: Single-Acting
Power: 12 VDC
Capacity: 2.0 Gal
Pressure: 3000 PSI
Flow: 2.0 GPM @ 1000 PSI
Ports: #6 JIC Male Connection
* Power Up / Gravity Down
* 2.0 GPM @ 1000 PSI
* Single solenoid operated holding valve
* 3000 PSI factory preset relief
* Made in USA (this one is $365 US)

So the questions would be, is the 2nd way better? Whats the difference between the two and are these prices good or where i can find something better/cheaper etc?

I need something that will be able to pick up about 2000-3000 pounds and if any info on who sells hydrualic cylinders (maybe a 4" 40/30) cheap would be appreciated too. Thanks.
