Those that need a pump and don't want to wait for the yard sales

I get a Surplus Center catalog
Saw 2 pumps that looked good for pumping out the tanks
$46.00 one >> RP-5 ROTARY HAND PUMP GPI

Or a cheap one that looks to be made of plastic for $30.00
If I was going to be dong a couple a month I think I would invest in the $45.00

$30.00 one >> TUTHILL SERIES 20 MANUAL TRANSFER PUMP
